ssh and the NAT

[recupero]

When I try to estabilish an ssh connection from outside my LAN,
my modem-firewall doesn't follow the configuration lines (the engine is called virtual server)

22 -> 22 on <my host address on LAN>,
but it takes the connection for itself, although at configuration the router says correctly:
<taking port 222 for my ssh>

I find no way to shut-down firewall and make it work as a modem
My firewall is a USR 9107 (there is a * saying: ssh not tested... would it be meaningful to me?)

Thank you for any suggestions.....

After trying and trying it works...
I guess I allowed all ports in
