Hi

I hope someone has some expirience with this:

I bought a Zywall 100 to protect my net. Before I had a
Linux based firewall.
Since I use the Zywall I cannot work with Terminal
Services anymore. The connection always breaks after some
seconds and I get a frozen logon screen.

When I turn off the firewall feature of the Zywall 100
everything works fine (but unprotected).

I tried several registry settings (TCP Params, etc.), but
I figured out, that it isn't a RDP problem, it's a Zywall
problem.

I even cannot connect to another Terminal Server in the
internet, same disconnection problem. Even if all outgoing
connections are open on the zywall.

The funny thing: even if the firewall feature is on I CAN
connect from lan to a TS in the DMZ without any problems!

Any ideas

Best regards

Tom
