SSL VPN Site-to-Site: only one side works.

cemendes
Hello guys!

UTM9. I have PPPOE on both sides. The UTM's SSL VPN connect fine, but only the client side can ping the server side of the VPN. The setup is very simple. I am pulling my hair off over this issue. I already read tons of messages from the list but, couldn't find any similar problem. Any ideas will be appreciated. I will post logs on the next thread.

    The tunnel is working perfectly, so the problem is elsewhere.  If you are pinging via numeric IP, then my guess is that you have a routing problem - either there is an overlap between the local and remote LANs or the devices on the non-responsive side don't have the UTM as default gateway.

    Cheers - Bob
    PS I just looked at the thread you separated this from, and, indeed, it appears that the non-responsive side is the one with a single-NIC UTM.  Assuming the single-NIC is in the 192.168.0.0/24 network, all you need is a static route (192.168.150.0/24 -> 192.168.0.15) in the edge router to send the response traffic back to the UTM.
