[ale] port forwarding with SSH

[John Wells]

As I've mentioned before, I have a need to forward all packets from a
machine on my company's network to an external machine on a kennesaw
server. I'm attempting to use a machine on my home network as the proxy.

The way I'm testing it is this:

My home machine listens (allows packets through the firewall) on port 80. 
I can nmap -p 80 mymachine when apache is running and see the port is
open.

I take apache down, run the command (as root) "ssh -L
80:dest.at.kennesaw.edu:1755 mymachine".

After doing this, I can telnet to port 80 when I'm logged into mymachine
and see that the port is being forwarded correctly.  However, when I try
to do the same from work, I get "connection refused".  nmap says the port
is closed (although I have it open and forwarded on my
firewall...remember, apache works on this port when I have it running).

Running tcpdump to see what's going on, my attempt at connecting from the
external (at work) machine looks like this:

mycompanymachine -> myhomemachine [SYN]
myhomemachine -> mycompanymachine [RST, ACK]

Anyone have an idea what might be causing this?  It would seem that since
the port's already configured to be open for apache, it should still allow
traffic through. Modifying /etc/hosts.allow seems to have no effect.

Thanks for the help!

John
