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.

So a little background of what I'm trying to accomplish. I'm basically trying to setup a Windows File Server using GCP VM Windows Instance. I have the VM setup and I have created a VPN connection between our office network and to the GCP VM network.
Now I'm trying to communicate between the two different subnets and I have to admit I'm kinda lost.
My office subnet is 192.168.72.0/24 and my GCP IP is 10.123.0.0 with my server being at 10.123.0.2
If I understand networking correctly I need to setup a route between 192.168.72.0 to 10.123.0.2? Or do I just need to create a firewall rule?
I'm using a SonicWall Firewall to establish the VPN connection to the GCP network.
I think I've been working at this too long for one day. I'm steaping away for a bit.
Thanks in advance.
If you set up a Site to Site, you should not need to include a route, you will if you setup a Tunnel Interface. But to me, it sounds like you just need to do a site to site. I dont think the tunnel will come up without the correct subnets, but just verify that the tunnel is up and then I would setup a packet monitor to see what route the traffic is taking when you try to ping from 192.168.72.0/24 to IP is 10.123.0.0.
I have a bit of a bizarre problem. I have a Hyper-V VM and I cannot connect to it via IP address on the host computer.
I intend to use it as an SQL server to host a database for a website while I test it, and the first step I can see in this endeavour is to make sure the IP addresses work externally.
Other PCs on the LAN appear to be able to connect just fine via the IP address on Remote Desktop. I cannot do so. I also cannot connect through SQL Management Studio (named pipes or TCP/IP). Although named pipes gives an error relating to being denied access as opposed to IPs which are just not found.
I have tried pinging both ways:
VM => Host : Always gives a "Destination Host Unreachable" error
Host => VM: Always gives a "Request Timed Out" error
As for netstat -a -n, I can see that the VM is listening to 3389 (default Hyper V port, which makes sense).
Regarding Firewalls, all have been turned off on all machines. I can tell that the firewall is not the issue.
If you need any more information to help me to diagnose and treat the problem, please ask me as I would like to get this sorted as quickly as possible.
Thanks a lot in advance.
Which windows server version do you use?
Windows Server 2016 blocks insecure RDP connections (https://support.microsoft.com/en-us/help/4295591/credssp-encryption-oracle-remediation-error-when-to-rdp-to-azure-vm).
Since RDP uses CredSSP you have to install the current Windows Patches.
Do you can ping the DNS server by IP address from your VM?
Is ICMP (ICMP = the thing you need for ping) on your host enabled?
Here is a Checklist for ICMP:

Solved,
Just switched to another physical computer and it was fine.
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 would like to create a local wireless without internet.
I would like to have the possibility to connect 50 clients and access to a website using a domain name.
That means, I need a DNS and DHCP.
I sreach on internet an I found a way to achieve that but not totally and i am not sure if it will work and if it is the best way to achieve that.
I can maybe have a mini PC (server) with ad hoc network and have the client to connect on the server but:
Will it be possible on a connection to assign a ip to the client and set a DNS server ip on the client as the same ip of the server.
I found mini PCs but how can I know if the PC will handle a lot of client ? Which network card to choose ?
I think also that a router and configure DHCP on it to distribute the IPs but I would like to have one box ready object as a mini PC.
I need an advice on the best way to go with what i want to achieve and materials i need to buy and good references.
For a linux domain controler you will need to install bind to host your own DNS. It's a little involved to set up, but necessary if your network doesn't have a DNS server. If you're using a windows domain controller you will need a server OS (expensive). If you only have 50 clients the DNS resources needed will be small and you could run bind from any old box, even a Raspberry Pi. You will also need a host machine for the "website" a.k.a. an intranet. This can be the same machine as your DNS server, but can be any computer on the network. When all is done you will have your router configured with the IP of your local DNS server. The DNS server will point your local domain to whatever box hosts the intranet website.
My goal is to have two laptops in a network. One is acting as a server, serving webpages to the other. The catch here is that neither is connected to the outside internet.
What I have done so far is setup WAMP on the server laptop, and it successfully serves web pages on localhost. Now I want to access these pages on the other laptop.
To do this, I had the server create an ad-hoc network and connected the other laptop to it, but I'm stuck - and I'm worried I'm not on the right track. I followed this tutorial but in the end I figured out that just explained how to spoof a text URL as an IP address, and not really what I was looking for.
So I guess I have two questions:
Is my method the best way to do this (with ad-hoc networks)? Is there some way to connect a laptop to a wireless router and have the laptop act as a server to another laptop?
If my WAMP and ad-hoc network should work, how do I connect other laptops to my server through the ad-hoc network?
Thanks!
I would suggest the first option: get a wifi router. Then you can assign static IP adresses from the routers private network or use DHCP server on the router. Hopefully you will have an option to reserve IP adresses on DHCP server so you dont have to check every time what IP adress the laptop acting as a server got. You use this address to access your web server. Also, you can use this router later as a gateway to the internet if you want.
In ad hoc mode you will probably get an address from 169.254.0.0/16 link-local scope, and you can check it by running ipconfig as #Robadob already suggested.
On your hosting laptop open cmd and call ipconfig look for the internal IP address on the network interface your hosting the ad-hoc network.
Enter that IP address into the browser on your client laptops web browser instead of localhost.
If that doesn't work, try other ip addresses listed by ipconfig (incase you used the wrong) and then check the properties of your ad-hoc network, windows firewall and any other firewall software to disable anything that might be blocking it.
An ad-hoc network is suitable option for what your doing, most people would probably use a switch or router though, however that requires hardware you probably don't have.
