The problem was that gtisr is a firewall (iptables), and I had to open
ports >1024 with source on amanda server. An alternative was to use
the amanda conntrack module, but I think it's simpler to open those
ports, provided that the source IP (and the physical iface) restrict
its use to the amanda server.

Cheers,

Rodrigo
