Question : PPTP connection to sonicwall cannot reach secondary site to site tunnel on same firewall

Have a client who connects to a sonicwall firewall using Windows PPTP and connects just fine. He can browse and see the LAN on that sonicwall device.

There is also a site to site tunnel going to another network on that same firewall but he is unable to reach it once dialed in.

I am not sure exactly where to start with this one. Unfortunately it is difficult to spend lots of time testing this problem because of time constraints.

Does anyone have insight on where the problem may be? Firewall rules? Routing? (I imagine it can be done, but maybe it can't?)

I don't think that Terminal Serer or remote desktop is an option unless absolutely needed.

Answer : PPTP connection to sonicwall cannot reach secondary site to site tunnel on same firewall

I believe that you have a split tunnel and not zero route; so only the traffic bound for the network behind sonicwall is going through; as you wish the traffic for the remote site-to-site VPN tunnel to pass through the sonicwall; then all the traffic from the remote client should first come to the sonicwall and then sonicwall should have policy to allow traffic from remote client to the site-to-site tunnel.

Please let know if you need more details.

Thank you.
