Since years I can access my 6.5sp4a servers trough a port-forwarding policy
(int. 8009 -> ext. 8009) on my firewall and that works great. Now I thought
it should be easy to change the external ports to some others like 8050.
But that's not work and I can't understand that. If I change my policies to
(int. 8009 -> ext. 8050) I only receive the certificate from this server,
but that's all and no login-screen. It works only, if the external and
internal ports are equal! Is that a routing problem of my firewall or what

Thanx for any suggestions
