it seems that both Time Capsule and Leopard Server both use port 548 for file sharing. So if I have both the server and Time Capsule with File Sharing turned on, any attempt to login will go to the Time Capsule and not to the server. If I turn File Sharing OFF in Time Capsule, I can than map port 548 to the IP of the server machine and users can properly login into the server again. However, turning File Sharing OFF disables both the internal and external USB drive connected to the Time Capsule from appearing on the network, so Time Machine won't work, since it can't see the Time Capsule drives. I am wondering if it's possible to change to port numbers on the Server or on the Time Capsule, so that they don't interfere with each other.
