[NBLUG/talk] SSH tunnels

[Omar Eljumaily]

So I'm still dealing with the issue of connecting to monitoring devices 
behind firewalls.  Static IPs will work when they're available.  
However, some cases will require an SSH tunnel.  PPTP and IPSec will 
work in some cases, but I can't guarantee that the device hosting 
network will have a subnet that is compatible with the VPN host's 
network.  I.E. for instance they both use 192.168.1.x for their subnets.

I'm trying to reach an http server behind a firewall from myseverxxx.com 
port 3001.  This is the command I use on the http server machine:

ssh -f -R 3001:localhost:80 myserverxxx.com -p 123 -N

But it doesn't work.  I use port 123 because I don't like to use default 
ports for ssh.  I don't get any error messages, nor do any error 
messages appear in my logs.  I've opened up port 3001 in my firewall on 
myserverxxx.com.  Is there anything obvious that I'm doing wrong?

There was a suggestion that ssh tunnels be a meeting topic.  I can talk 
about them, and what I'm using them for if I can get them to work, if 
there's interest.

Thanks,

Omar
