IPSec Tunnel strange problem

I set up a IPSec tunnel between a Linksys WAG54G (Network A) and a
OpenSWAN server behind a USR9106 gateway (Network B).
The tunnel is established correctly, A can pings B and viceversa.
The problem is that randomly the tunnel hangs, it seems esablished but
networks can not ping each other anymore.
If I try to re-establish the tunnel, it seems to be esablished
correclty, but I can not ping.
When I reboot USR9106 gateway all returns to work, so the problem seems
to be that gateway but it only forward port 4500 to the OpenSWAN server!

Any ideas?

Thanks in advance,
Heruan
