hope you all doing great.
I have a little issue with my server network connection. I have been using this ISP for a while now, my set up was by connecting the router to different router then to the switch, it was going great. But I have changed my ISP to new one with faster Internet, however after I did this I connected my switch directly to the ISP router which now gave me an issue. The server keeps on connecting fine but it reach a point where it refuses any traffic and my Web server just gets down.
So I would like to ask of you if you have any clue on why is this happening?
I would like to mention that when this happens, I need to reset my server ip address and router as well and get a new set of ip address connection to set this over again.
Thank you.

I am using (airtel xstream fiber) connection and trying to do port forwarding. I forwarded port 3000 of wan and direct it to my system ip address 192.168.1.2 on port 3001.
Node server is running on my system on port 3001. And I can access my hello world website locally using 192.168.1.2:3001. But when I am trying to access using public ip, it show this error code "ERR_CONNECTION_TIMED_OUT".
Also, I found my router port 3001 is open using online port checking tool/website.
So, Can anyone please tell what could be reason behind this ? Is this the problem with windows.
You first need to check what ports are open by your ISP. If your ISP is giving you a local ip at the router. Basically, creating a ppp connection. It may be using a cg nat. In that case you need to buy a static ip, without that none of the traffic will be Directed to your router. Let me know if you find something, I'm currently looking to get xstream airtel as well.
No there is no need for static IP to be access server remotely. As of now, What I see is airtel allocates new ip every 24 hr or when router got disconnected. To access your server remotely you can do two things. First one is more secured.
Change Primary IP adress of your airtel router and use Portforwarding so that its port 80 will be free for you.
Enable DMZ and point it to your local server IP. [192.168.X.X]. In this case all of your ports of the device are exposed to internet. If you want to be secure. Make sure add another router between server and airtel router and enable port forwarding.
But in this case there is a catch, When you try to access your local website using public ip (which you can see on google search) it will redirect you to airtel router panel. But when you try to access it using other device (not server otherwise server will get disconnected) connected to internet using other network(other that your current airtel router like JIO sim, Airtel Sim, etc), It will work excellently.
To get rid of dynamic ip use no-ip services. Its website will help you more. Basically, It is dynamic dns server where you will get free domain. That will get update regularly while its service running on your system. To use other dns provider service like godaddy you must need an static ip.
Guidance on how to connect to SQL Server 2012 needed.
I am on Windows 10 Home Edition
I have set up SQL Server Express to allow remote connections on my database machine to serve up data to three client machines.
Firewall has been set for ports - check
Allowed mixed mode logins - check
Setup IPs through SQL Configuration Manager - check
The server is something like 192.168.1.40,1433 and I can login successfully through SQL Server Express on my client machines. I had a long LAN cable running along the floor which is not optimal. So, I went to the store and bought a router so that I could connect wirelessly but have limited experience in networking.
After, installation of the router I can no longer connect to SQL Server. This makes sense since there is another piece of hardware in the chain.
After doing an IP config on the command line I see that the IPV4 address has changed. I assume I am not picking up the private IP address of the router rather than the modem that I was initially connected to.
Should I be port forwarding?
What are my options?
I explored what I thought may be reasonable leads to get this working.
First, I tried to create a virtual server (I also assume this is how to port forward on my particular router). I didn't really know what to put in five fields that were given other than server name and Protocol TCP or if I was on the right track at all.
The other three fields consist of:
External Port, Internal IP, and Internal Port
If this is a reasonable solution can you let me know what to put in these fields and any changes to the SQL Server configuration or firewall might be?
Should I VPN ?
After exploring this option on google I also notice people saying, "set up a VPN is the correct way to go." However, I don't really know how to do this. The only VPNs I know of are external VPN providers. It seems that I would be setting up a VPN server if I am not corrected(maybe on the server computer) and connecting via my client machines.
Any clarification or direction would be greatly appreciated. I am sure I have missed the mark on many things here but still would like to make ground.
I have been trying to create a server in one network but the people in another network cant connect to my server? Even though my IP is dynamic (dhcp :yes)
I want to create a server in one network but want to connect people to that server present in another network. I started a server "eg: 103.251.9.85:27015"
even though my IP is dynamic, they can't connect to my server? Help me ...
who ever knows my IP address and port number will connect to my server, but when I am starting a server they cant connect.
Your server needs a DNS record.
DHCP is great for allocating an IP address - but you then have to manually tell everyone what the IP Address is.
You should define your Server in your DHCP configuration, assuming that there is a DNS Server also.
By default the DHCPD informs the DNS Server - assuming they are both under your control.
First ensure that you have network connectivity between the nodes - there can be NATs, Firewalls and a lot of different reasons why you can not connect. My advice for you would be to try and use netcat.
Once you have netcat on your computer - start it in a server mode. Then ask your friend to download netcat on his/her computer and connect to your IP address. If you can establish connection - great. Then make a question regarding your server program. If netcat fails - then there is network connectivity issue and you will find better help for those issues in the power user or network engineering Stack Exchange sites.
Okay, so I'm hosting a VPS for someone using Virtualbox. I've setup a server for that guy with a NAT network type ( this way I could port forward the entire thing so it can be used for what the guy wants ). The guy can use remote desktop to connect to the server, however. Everyone who tries to join his game, gets the same IP. I guess this has something to do with the guest settings, if I'm not mistaken.
Could anyone provide me any more information about the reason behind these IP's?
I'm running on the latest version of Virtualbox with a windows 7 enterprise 64bit version where a SA-MP server is being hosted on.
Everyone who connects to his server gets the ip; 10.0.2.2. Any help would be really appreciated
If a machine is located behind NAT, then all of the incoming connection will always be recorded only from a single source, that is you router's IP. It's normal since all of the incoming connection will have to go to the router first.
(I have not put code in this question since the actual code probably doesn't matter here. If you say it does though then I can edit the question later to put it in.)
I'm new to using winsock2 or any other networking API for that matter. I have a very simple server application and client application in which the server sends a string to the client and then disconnects.
The applications work fine when I use localhost or 127.0.0.1 as the inet_addr() argument, but when I use my "real" IP, the client application just gets WSAECONNREFUSED and the server doesn't see it. I made sure that the port was the same for both applications and that also the protocol was the same.
[Edit] I have come back to this issue after abandoning networking for a while. I think this may actually have something to with the fact I am using a router, and not something in my code.
WSAECONNREFUSED is an active refusal of the connection by the peer or by an intermediate firewall. If it was the peer who issued it, it means you got the IP address or the port wrong, or else you got it right but the server isn't actually running; anyway, nothing is listening at that IP:port. If it was the firewall, adjust it.
Did you use htons() on the port number?
inet_addr() only works with IP address strings, you have to use gethostbyname() or getaddrinfo() to resolve localhost or any other hostname string to an IP address.
WSACONNREFUSED means the connection was actively refused on the remote end that you are trying to connect to.
If the server machine is refusing, that means either there is no socket listening on the requested IP:Port, or that there is one but its queue of pending client connections is full so it cannot accept a new connection at that moment.
If a router is refusing, that usually means the router is not configured to forward inbound connections for the requested IP:Port to a machine on the router's network. If you have a server running behind a router and are trying to connect to it using the router's public IP address, then the router has to be setup for port forwarding.
If a firewall is refusing, that usually means the requested port is not open.
Either way, there is no way for the client to know in code why the connection was refused. All it can do is wait for a period of time and then try again.
