i think one of us doesn't understand the problem solved by
port-forwarding...?
turns out the vast majority of these connections will be coming
from beyond a remote firewall (remote from where the server is
located on the 'net):
client
192.168.9.9
|
192.168.0.1
client firewall
11.22.33.44
|
| internet
|
22.44.66.88
server's firewall
10.1.1.1
|
10.1.2.3
server
the server can't open a port on the client machine, cuz it can't
get past the client firewall. the client CAN ssh past the server
virewall (that's how the latter is set up) to the server itself
and establish a remote-to-local forwarding rule. if the server
can be made to chat with a localhost interface using a port to
match the forwarding setup, it will work -- for one user per
loopback interface.

about those dummy interfaces... can they be made into loopback
devices? and if so, how?
