I have 2 draytek vigor 2820 routers setup with a PPTP VPN

Router 1 is the main office and has the
1st IP of 192.168.10.252 (local LAN)
Sub class C
2nd IP of 10.170.101.250 (3rd party network)
Sub Class C
From router 1 I have a static route sending all 172.22.215.0 traffic to the gateway of 10.170.101.251

Router 2 is a remote branch and has the
1st IP of 192.168.12.252
Sub class C
2nd IP of 192.168.10.252
Sub class C

I can ping router 1 from router 2 and have setup the VPN ok, what I need to do is now route to the IP address 172.22.215.66 but I cannot get to this address from router 2. When performing a tracert it sends the traffic to the internet and not down the VPN. i would appreciate any help on this matter as I am working on a very short time scale.

It looks like you will need to change the VPN profile for the remote site, go to the VPN profile and look at the TCP/IP settings, click the More button and enter the IP range/subnet of the 172 network on there. Once the VPN tunnel is re-established it should be aware that that IP range is available through router 1.

Thanks for your reply i have entered the 172 network in to more but it doesent seem to have fully resolved the issue.

to clarify if i use a dial in VPN connection to router 1 i can ping the 172 network ok but even with the newwork added as suggested i still cannot route to it but i can router to anything else connected tro router 1 with out any issue it has to be something silly i am missing?

Thanks for all the help

i have now resolved with the additionl help of the draytek helpdesk the reason the VPN did not forward the network traffic was due to the fact i hade entered 172.22.215.0/32 instead of 172.22.215.0/24

i hope this helps others resolve simular issues

cheers
