I have a problem accessing my website created using Visual Studio on my local pc.
The pc is using Windows 7 and a static ip address has been configured. I have added a hostname "192.168.0.1 hosts myweb.mylocal.com" on c:\windows\system32\driver\etc.
On IIS I have configured the binding myweb.mylocal.com with impersonation set enabled and windows authentication is enabled.
The user login just keeps prompting even though I have entered the correct username and password.
Yea 192...* is router reserved IP.
I had the same issues with Windows 7 and and its due to IPV6.
Try disabling the IPv6 Protocol in "Control Panel\Network and Internet\Network Connections" and right clicking your stablished connection to your router, unticking the IPv6 and leaving the IPv4 selected to see if that will make a difference.;
Your local IP is more than likly :::1 or something along then lines!
-- Update
Where you have set you ip 192.168.0.1 to route to your local domain, try setting it to 127.0.0.1 so that it loops to itself and not via the gateway, Or you can leave it as it is and add the rule to your router to send traffic from the HTTP Port 80 to your PC.

I have a FritzBox 7362 SL running with the following config:
DynDNS (only IPv4 address mapping)
port exposure to a local web server (ports 80 and 443)
remote access via MyFritz activated
no other remote access or VPN activated
Everything worked fine for years. Today I changed registered a new DynDNS and adjusted the settings for the FritzBox. The new DynDNS now also supports mapping to IPv6 addresses.
After that, my webserver isn't accessible anymore. Instead, now the login page of the FritzBox appeares, for both, HTTP and HTTPS. Login is refused, thank godness, even with valid credentials.
I found out, that this is only true when the IPv6 address or the new DNS name is applied. The DNS name now also maps to the IPv6 address. Applying the IPv4 address accesses my webserver (when reactivating the port exposure)
I triple checked all the FritzBox' setting; there is definitely no active remote access setting left. I also removed the port forwarding setting and the MyFritz exposure (and restarted the box, of course).
Does anyone have an idea about this?
I have a few web-based local applications for home-automation purposes, those are accessible through IP addresses with port numbers something like http://192.168.1.100:8080.
What I am trying to achieve is to link each individual IP and port number combination to an internal domain name, so that anyone can use domain and subdomain names rather than IP addresses.
For example a person can specify a URL of http://kitchen.home rather than an IP address with port number URL such as http://192.168.1.100:8080.
At the same time http://192.168.1.100:8081 could be mapped to a domain name such as hall.home so that a URL of http://hall.home could be used instead of that IP address and port number.
The access to a server should not require having to modify the hosts file of individual PCs but should be some kind of a domain name server that maps domain names to IP address and port number for any PC on the local network.
I have set up a DNS server on a PC running bind9 as a DNS server under Ubuntu 20.04 on my home network in order to have my own special domain names.
A few details about DNS and proxy server with HTTP
To map several different subdomain names within a domain to specific ports on the same PC, you will need a proxy server installed on the the PC as well as a DNS server for the local network. Domain names are mapped to a specific IP address with the DNS protocol and are not mapped to a specific port at the IP address.
In my case I have the same PC hardware with Ubuntu 20.04 that has (1) Bind9 for my DNS server and (2) Apache for my proxy server. I could use two different PCs, one as a DNS server to resolve domain names to IP addresses and the other offering various services accessed either through a single IP port using a proxy server listening on the port to dispatch connections to the services or directly to the service by specifying the correct port number of the desired service.
For example http://kitchen.home/ in a browser would instruct the browser to open a TCP connection to the IP address represented by the domain name kitchen.home using port 80, the default HTTP protocol port. A DNS server is used to resolve the domain name kitchen.home to an IP address. With a URL of http://kitchen.home:8081/, the browser will ask the DNS server to resolve the domain name kitchen.home to an IP address and then open a TCP connection to that IP address but using port 8081 rather than the standard HTTP port 80.
So for http://kitchen.home/ to map to port 8080 at that IP address and for http://hall.home/ to map to port 8081 at that IP address you need to combine a DNS server, which resolves the domain name, with a proxy server residing at port 80, the standard HTTP port. The proxy server will then redirect the request to a different port on the PC selected based on the subdomain name, hall or kitchen, of the entire domain specifier, kitchen.home or hall.home.
See https://stackoverflow.com/a/58122704/1466970 which describes setting up Nginx as a proxy server.
The Apache web server can also serve as a proxy server which is what I'm looking into. See this tutorial from DigitalOcean, How To Use Apache HTTP Server As Reverse-Proxy Using mod_proxy Extension as well as Setting up a basic web proxy in apache.
My environment
I have a Windows 10 PC downstairs with a Ubuntu 20.04 PC upstairs communicating through an Arris router to my cable internet provider. Both PCs are connected to my local home network with WiFi.
The Ubuntu 20.04 PC is my Subversion server using Apache web server. I spend most of my time with the Windows 10 PC downstairs, using PuTTY to connect to the Ubuntu PC with one or more terminal windows when needed. I plan to work with Visual Studio on the Windows 10 PC accessing Subversion through the Apache web server as well as using the Ubuntu PC as a database server (MySQL) and web server (Apache with Php) and microservices (golang and node.js).
I wanted to setup a DNS server on the Ubuntu PC and then point my Windows 10 PC to use the local DNS server for a special domain name while using standard DNS servers such as Google at 8.8.8.8 and 8.8.4.4.
What I did
The procedure I followed was (see How to Configure BIND9 DNS Server on Ubuntu 20.04 and see as well Domain Name Service (DNS) and Everything You Need To Know About Ubuntu DNS Servers):
install bind9 using sudo apt install bind9
create a firewall rule sudo ufw allow Bind9
modify the file /etc/bind/named.conf.options
modify the file /etc/bind/named.conf.local
create a copy of /etc/bind/db.local for my new domain name, home.x
modify the new file, /etc/bind/db.home.x, with the correct rules
The domain name I wanted to use locally was home.x with the idea that if I entered a web site URL of http://www.home.x/ the resulting page would be the Apache web server on my Ubuntu PC. Or if I entered http://home.x/svn the result would be the Subversion repository on my Ubuntu server.
Note: in order for Subversion access through Apache, I had to set that up. See enabling Subversion access via Apache web server and DAV on Ubuntu if you are interested in that.
Details on changes and modified files
The Ubuntu PC has an IP address of 192.168.0.4 on my local network. In the descriptions below, this IP address is used where ever the Ubuntu PC is referenced.
I added a forwarders section to the file /etc/bind/named.conf.options in order to forward any DNS requests that were unknown to my Ubuntu server to some other DNS server. The IP addresses I copied from the list of DNS servers returned by the Window 10 command ipconfig /all which I ran on my Windows 10 PC. The changed file is as follows:
rick#rick-MS-7B98:~/Documents$ cat /etc/bind/named.conf.options
options {
directory "/var/cache/bind";
// If there is a firewall between you and nameservers you want
// to talk to, you may need to fix the firewall to allow multiple
// ports to talk. See http://www.kb.cert.org/vuls/id/800113
// If your ISP provided one or more IP addresses for stable
// nameservers, you probably want to use them as forwarders.
// Uncomment the following block, and insert the addresses replacing
// the all-0's placeholder.
// forwarders {
// 0.0.0.0;
// };
// following forwards are to Google DNS servers at 8.8.8.8 and 8.8.4.4
forwarders {
8.8.8.8;
8.8.4.4;
209.55.27.13;
};
//========================================================================
// If BIND logs error messages about the root key being expired,
// you will need to update your keys. See https://www.isc.org/bind-keys
//========================================================================
dnssec-validation auto;
listen-on-v6 { any; };
};
After changing the file /etc/bind/named.conf.options, I then ran the check utility, which found no errors, and then restarted the bind service.
sudo named-checkconf
sudo systemctl restart bind9
Next I added a new zone directive to the file /etc/bind/named.conf.local to create a DNS entry for my new, local domain name home.x. The modified file looks like:
rick#rick-MS-7B98:~/Documents$ cat /etc/bind/named.conf.local
//
// Do any local configuration here
//
// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";
zone "home.x" {
type master;
file "/etc/bind/db.home.x";
};
Finally I needed to create the file /etc/bind/db.home.x specified in the file directive of the zone directive. I did this by starting with a copy of the existing file /etc/bind/db.local by using the command
sudo cp /etc/bind/db.local /etc/bind/db.home.x
I then modified the file /etc/bind/db.home.x in order to specify the rules I needed to resolve the domain name of home.x as well as the subdomain of www.home.x to the IP address of my Ubuntu PC. The modified file looks like:
rick#rick-MS-7B98:~/Documents$ cat /etc/bind/db.home.x
;
; BIND data file for local loopback interface
;
$TTL 604800
# IN SOA home.x. root.home.x. (
2 ; Serial
604800 ; Refresh
86400 ; Retry
2419200 ; Expire
604800 ) ; Negative Cache TTL
;
# IN NS ns.home.x.
# IN A 192.168.0.4
# IN AAAA ::1
ns IN A 192.168.0.4
www IN A 192.168.0.4
At this point I could test that things worked from my Windows 10 PC by using the nslookup command from a command window. I tried it first without specifying the Ubuntu PC IP address and then with the Ubuntu PC IP address
C:\Users\rickc>nslookup home.x
Server: dns.google
Address: 8.8.8.8
*** dns.google can't find home.x: Non-existent domain
C:\Users\rickc>nslookup home.x 192.168.0.4
Server: UnKnown
Address: 192.168.0.4
Name: home.x
Addresses: ::1
192.168.0.4
I then used the Windows 10 Control Panel (Control Panel > Network and Internet > Network Connections) to see a list of my network adapters in order to modify the DNS server addresses my WiFi adapter was using. This setting is found by doing a right mouse click on the adapter to pop up a floating menu, select Properties to bring up the Properties dialog then select Internet Protocol Version 4 then click the Properties button on the dialog and modify the DNS server address. Below is a screen shot of the dialogs.
After modifying the DNS server address, I retried the nslookup without specifying a DNS server address and the command finds home.x:
C:\Users\rickc>nslookup home.x
Server: UnKnown
Address: 192.168.0.4
Name: home.x
Addresses: ::1
192.168.0.4
When I tested a URL of http://www.home.x/ the test page of my Apache web server is displayed. When I tested a URL of http://home.x/svn the web browser showed the directory tree of my Subversion repository. When I access my Subversion repository with http://home.x/svn/trunk/ within the Ankh Subversion plug-in with Visual Studio 2017 it works.
Other thoughts
One issue with this setup is that if my Ubuntu PC is not up and running then the Windows 10 PC will not have a functioning DNS server until either the Ubuntu PC is brought up or the DNS server address is set back to the original setting on the WiFi adapter. Previously, it was set to discover a DNS server. It may be that I can change this back and from a specified DNS server address, the IP address of my Ubuntu PC, and my Windows 10 PC will discover my Ubuntu PC as a DNS server anyway.
DNS names are independent of port numbers. A dns record correlates a name to an IP address. If you want to omit the port number from urls, you either need to host on the default ports (80/443), or use a proxy.
With a home network, the dns can be tricky, and usually depends greatly on the specific router you have. Your options are basically:
Maybe your router has an interface for defining host overrides. OpenWRT has such a thing, and some routers have a similar dns server on them that you can add host entries to.
Get a public domain name. You can have an A record for example.com that points at a local network address. The server itself may only be accessible inside your network, but the dns will be available anywhere.
Run your own dns server and tell your router to use it as the default resolver for your network.
Maybe mDNS could suit your needs for .local domains.
I have three Windows hosts on the same private LAN, each hosting an IIS default website. One host is running Windows 7 Pro, while the other two are running Windows 8.1 Update Version 6.3 (Build 9600).
Other computers on the local subnet can open the default website on each of the 3 hosts by entering each host's private IP address in a browser.
However, when I Port Forward port 80 on a gateway router in turn to each of the 3 hosts private IP address, then enter the public IP of the gateway router into a browser on a computer outside of the private network, only the Windows 7 host displays its default website.
When Port 80 is forwarded to either of the two Windows 8.1 Update hosts, the browser reports "This webpage is not available. Details: The host took too long to respond." Additionally, no record of the request appears in "C:\inetpub\logs\LogFiles\W3SVC1\u_exYYMMDD.log" on the host.
All three hosts have their Windows Firewall Inbound Rule "World Wide Web Services (HTTP Traffic-In)" set to Profile: All, Enabled: Yes, Action: Allow, Override: No, Program: System, Local Address: Any, Remote Address: Any, Protocol: TCP, Local Port: 80, Remote Port: Any, Authorized Users: Any, Authorized Computers: Any, Authorized Local Principles: Any, Local User Owner: Any, Application Package: Any.
Furthermore, disabling both Windows Firewall and Windows Defender made no difference. I have not installed any other security or firewall systems.
It appears that something is preventing port 80 requests from public ip addresses from reaching Windows 8.1 Update IIS. Yet the success on Windows 7 demonstrates that the gateway router is properly forwarding outside traffic to the assigned IP address.
What could be blocking the public ip port 80 requests to Windows 8.1 IIS, and how can I correct it?
Problem solved. It turned out the cause was Check Point VPN v98.60.202, from Check Point Software Technologies. I had installed this software to connect to a corporate client's internal network.
I suspected this was the cause because of how VPNs work, so I had previously closed the VPN software, but that didn't solve the problem. I actually needed to completely uninstall the Check Point VPN software and reboot the computer to remove the hooks it makes into the Operating System's TCP/IP stack. That allowed IP addresses outside of the host's subnet to again be served by IIS 8.5.
How Can I Access My Locally Hosted IIS WebSite from Remote Computer By My IP Address ?
You have to check you ip here, make sure that you are forwarding port 80 (especially if you're in a locale home network), and then you could access your server by http://<server_ip> e.g. http://192.168.0.6
Note that as long as you don't have a fixed (static) ip, your ip address might change, and you'll have to recheck it.
Another note- The default HTTP port is 80, and by using port 80 you could access your server via browsers without writing the port number. If for any reason you like to switch port, make sure your forward that port number and access your site by http://<server_ip>:<port_number> , e.g. http://192.168.0.6:8080
if you are using some other port. then you can go with http://<ip_address>:<port_no>
I am hosting an asp.net MVC 3 application on my local IIS 7.5 server. People can connect using my IP and the port I set. I can connect by typing localhost:port in a browser. If I type the IP:port however, the browser says it cannot connect.
Using wamp and other hosting programs (and even IIS at one point if memory serves), I could always connect using my own IP.
How can I set IIS to let me connect using my own IP? Or is the problem somewhere else?
My firewall is disabled, the port is forwarded and other people can connect just fine (people outside my LAN) and I have tried 3 browsers.
You cannot connect to your IIS using static IP, but, howerver you can by adding your Static IP as a lookup entry.
