thanx for this hint! I will try to set RemoteAuxPort but I suppose it
will change nothing, as the gateway doesn't block anything on the
encrypted link. all traffic is passed through to the database server.
and as far as I understand events the first packet is sent from the
client to the new RemoteAuxPort, so the firewall on the client does
not mater also.

any other ideas? packet fragmentation? anything?

thank you!
