> Firewall?

Kind of, namely an IPSEC tunnel between my Linux box with FreeS/WAN
and a gateway with OpenBSD.  :)

However I allow all traffic through the tunnel, so the firewall should
be invisible to the programs.  All the usual protocols/services seem
to work.  Of course there may be implementation bugs that cause
strange behaviour.

Ok, I'll try to find out where the packets are going then.
