[jadmin] File transfer in Jabber 2

[Alejandro Cabrera Obed]

Dear all, I have a Jabber 2 server with some PSI clients in my LAN. When
I start a file transfer it doesn't work at all because I suppose I have
a local iptables firewall that blocks the p2p connections.

Can you tell me the way jabber 2 treats the file transfer ??? In case
the file transfer is arranged between clients, what ports should I allow
in my firewall ???

Special thanks

Alejandro
