Hi,

I have followed the guide that came with the 3900 to set up a lan to lan VPN (Main mode).
Site A (3200) has 192.168.10.0/24.
Site B (3900) has 192.168.29.0/24.
They are linked in my lab via 10.20.1.2/24 (wan2 ip on 3200) and 10.20.1.3/24 (wan1 ip on 3900).
The VPN is established & shows green (encrypted).

I can ping from 192.168.10.1 (3200 lan) to 192.168.29.1 (3900 lan) and visa-versa (via the diagnostics menu on each router).
I can ping from a laptop (192.168.10.100) in site A to laptop in site B (192.168.29.10).

But I cannot ping 192.168.10.100 from 192.168.29.10. (so from the lan in site B back to site A) ...

However 192.168.29.10 can ping 192.168.10.1 (the lan ip on 3200).

I need all devices in site A to be able to talk to all devices in site B and the other way around.

Any clues?

Thanks, Filip

PS Both routers run the latest firmware, 3200 = firmware 3.3.7.2, 3900 = 1.0.6
