[LUGSB] SSH through routers?

[Michael Hrivnak]

In short, no.

But, there are other options, such as some sort of a VPN.  This requires 
access to some other system on the internet, which I'll call somewhere.com.  
>From your machine:

ssh -R 2222:somewhere.com:22

Leave that connection open.

Then from any system on the internet, ssh to the remote machine on port 2222, 
and it should forward the connection through the previously-established ssh 
tunnel to your machine.

Note that port 2222 was picked arbitrarily.

A more elaborate and comprehensive solution would be something like OpenVPN, 
but that may be a bit much for your situation.
