Internet over a VPN connection

[Littlejohn2003]

Ok I got everything working that I need.
However, when I VPN with the standard Microsoft PPTP client on XP I can't get internet.
Here is my config with the 10.10.10 replacing my real public IP's.

I had to fix this on the Windows XP side. This is what I did to fix it. I turned off "Use gateway on remote host" in the VPN-TCP/IP Props and added a route for the following:

192.168.2.0 to use interface 192.168.4.x
192.168.3.0 to use interface 192.168.4.x

So here's my question. Is this the correct way to do this? Or is there a more efficient way to do this? (which I'm sure there is, just don't know that much about PIX)

All we did was uncheck "use remote gateway on host"

You shouldn't need anything else.

 

[Littlejohn2003]

You just unchecked the "use remote gateway on host"? When I did that, my local machine did not know how to route the packets to:
192.168.2.x
192.168.3.x
Considering that my VPN subnet was:
192.168.4.x

So I had to manually add a route on my workstation:
route add 192.168.2.0 mask 255.255.255.0 192.168.4.x (x being the workstation VPN IP address)

I'm just curious if this is what people normally go through. Or if there's a better way to do this than having to connect the VPN then kicking off a VBScript to add the routes.

(I wrote a short VBScript to pull the VPN IP address out of WMI and put it at the end of the 'route add' statement since the VPN IP is usually always different)
