I connect to work's VPN on my laptop. In my last laptop (XP), I added a route so that I can RDP into my work laptop from my desktop while the laptop is on VPN. But now, with the new laptop with Windows 7, the same route entry fails and as a result, the moment my laptop is connected to work's VPN, I can no longer access it from my desktop. Here's what used to work on XP:

route -p add 192.168.1.2 mask 255.255.255.255 192.168.1.7 metric 1

Laptop is 192.168.1.7 and Desktop is 192.168.1.2

Please help me figure this out.

What is the error, and what VPN software and version are you using? –  Paul Aug 29 '12 at 4:27
    
I'm using Aventail 10.5.3 for VPN. There is no error. It adds the route fine but when I try to ping 192.168.1.2 (desktop), it times out. –  Kingamoon Aug 29 '12 at 4:30
    
Can you edit and add the results of netstat -rn once you have established a VPN session and added the route? –  Paul Aug 29 '12 at 4:31
    
The weird thing is, using the above route, creates the permananet one but also adds an entry to the Active Routes with a Metric that's n+25 where n is what I entered in the route command. I didn't see that happen in XP. –  Kingamoon Aug 29 '12 at 4:46
    
This may well be a result of the VPN software upgrading as much as the OS. This issue is common to VPNs in general: at the headend, administrators define whether the client should permit access to the local lan, and any other IP address while the VPN is established. It seems likely they have disabled local lan access, and this just wasn't very effective on XP. Perhaps ask them? –  Paul Aug 29 '12 at 5:30
