* It's called PORT.USAGE, my bad.

I don't know where it would be on your system, but it is installed in the
docs directory included with the amanda package. On my redhat system it is
in /usr/share/doc/amanda-server-2.4.4p1.

No, amcheck passes since it uses the ports that are usually allowed by the
firewall. The problem is when the data stream starts, it is on a port sent
by the server, so unless the firewall examines the packets, it doesn't know
to allow those through. If the others work and one doesn't, I would check
for a firewall installed on the failing machine itself, and also double
check that the client is compiled with the same --udp-portrange and
--tcp-portrange as the working servers.
