Hello,

I'm trying to setup a situation where I connect to a VPN on another ISP IP. Once the VPN is connected would I technically be surfing the internet on another ISP IP?

Can anyone link me, or explain how this can be done. When I setup VPN on a server for the Client to connect to, it just disconnects all networking for the server. Do I need another network port for this.

This is the pretty standard VPN server setup. Sounds like you are doing it in reverse. The client software DOES force all the traffic though the VPN by default so it in effect cuts all access to the local internet and sometimes even other machines on the local subnet. This is a configurable option controlled by the server.

The server should not really have much impact it only routes the new single IP over the VPN all other traffic flows as normal. You generally don't have to do much special to get this to work other than make sure your router has the proper ports mapped.

It does get very messy if you are trying to test this with the client and the server on the same network...ie both device plugged into the same network in your house.

Many people use OPENVPN without trouble their setup instructions are pretty clear. There are even youtube videos on how to do this.

I will look into OPENVPN.

I am hosting a website for a client and they want the site to only work on a single PC at their remote location, while I am hosting it in a different location. The only idea I could think of was to block the website from all ISP IPs except the one the client PC is VPNing into. Does that make sense? IIS7 can deny access to certain IPs, but I'm not sure if it will work with private IPs.

IP don't mean a lot when there is stuff like NAT involved. You can pretty much allow or block any ip the problem would be if you overlap private networks. Sounds like lots of effort when you could use other methods. I would be looking to have the server validate the user in another way. You would think the client pc could send you a certificate or something to validate its identity. If you are worried about encryption I would just use HTTPS
