That is exaclty my situation. My son is at a school and is behind a file. My home system is behind a file will.
the vtund simple solves that problem by creating a tunnel and then you can directly ssh to any of the systems.
Heres what I have
son's system --- filewall ---Internet ---- filewall--- my system
other systems on
my local network
After the vtund program heres what I tetSons system<------>my system(acts as a router)
other systems on my home networkhttp://vtun.sourceforge.net/
I discovered that telnet works best since the tunneling software encrypts and compresses.
It took about 5 minutes to set up.

hi all-
thanks for all the comments. let me explain my setup better (i gave a poor description of it before):
we use a sonicwall firewall, and behind it are several computers. i have two IP addresses: one for the firewall unit, and one that i use for port forwarding through the firewall to a computer (IPs made up). the firewall is in 'stealth' mode.
internet
--- firewall ('external' ip address: 10.0.0.0 with a web-visable hostname; internal ip address: 3.0.0.0)
-- box 1 ('external' port forwarded ip address 10.0.0.1 with a web-visable host name, which points to the internal ip 3.0.0.1)
-- box 2 through 5 (internal ip 3.0.0.2 through 3.0.0.5)
what i usually do is:
# ssh to the port forwarded, web accessible box
ssh -X [EMAIL PROTECTED]
# ssh from that machine to other machines behind the sonicwall firewall that do not have port forwarding hostnames/ip addresses)
ssh -X [EMAIL PROTECTED]
maybe my setup is inefficient? should i setup in my firewall the second IP address (10.0.0.1) to port forward SSH at higher ports to the other boxes? can i do that (say, 2222 for box2, 2223 for box3, 2224 for box4, and so on)?
thanks, doug
