I'm trying to connect to my home using VPN. Problem is my work pc is on a LAN where the end users have fixed IP's. The router/t'interweb gateway also has a fixed IP on the LAN. When I try to connect to home it makes the connection but then freaks out because the VPN trys to assign a client IP address, while the network adaptor says "don't think so mate you're this IP".

Is it possible to have a fixed IP pc on a LAN and a VPN running at the same time?

edit: 99.9% sure firewalls aren't the problem but the work router might need a fettle to allow 1723 tunneling.

are the ip address ranges the same for the home pc and the lan? if they are the same then you'll need to change the ip address of the home pc.

VPN is something I've always found conceptually clear as crystal but implementationally clear as mud.

Extend the IP range to cover the work IP as well?

change the home range to 1.60 to 1.65 and it should work

When you use your VPN you become "virtually" a PC on your "work" network even though you are physically remote.
You probably have some proxy settings within your browser which may need changing or adding to align with your office internet gateway settings.

because all your traffic is now going via your work connection and they block port 80 outbound traffic. probably need to use their proxy.

VPN = pain in the arnoos

disco_stu's solution seconded. Make sure they are separate IP ranges and all should be fine (sitting here VPNed to work right now).

Go to the Properties of the VPN connection, then TCP/IP Properties, Advanced, and make sure "Use default gateway on remote network" is NOT ticked.

All internet traffic will now flow through your own gateway, but you'll still be able to Remote Desktop / VNC to your work machine and use it (if that is what you are trying to do)
