What you would want to do is ssh FROM your "linux server" TO something on the outside, such as "my_other_server" or something else both servers can get to.
You would use ssh remote port forwarding.
[user@linux_server]$ ssh -R8022:localhost:22 my_other_server.com
Explaination: Connect to my_other_server and open port 8022 there which will forward back to me ...

You can use a VPN of sorts to get this working, but it would require you to have a server that the inaccessible server can access. Then you can set up OpenVPN on the server, your PC, and the firewalled server, enable client-to-client, and you're done. http://openvpn.net/howto.html

The problem is that you are using a kludge called NAT to connect multiple computers behind a single IP. This prevents you from selecting a specific computer in your local network when you connect from the outside (since you only have a single IP to select).
However if you have control over your firewall (cq the firewall in your router/gateway/modem/switch ...

That is correct, in theory, be be aware of a few complications:
Most NAT solutions (assuming you are talking about SNAT/masquerading) will only use one address per interface, so "number of outgoing IP addresses" will be limited to 1 in most cases.
It won't be using the full range of 65,536 possible ports either.
Some mappings will be longer lived than ...

You don't have to register them all. You can lease a block of address. Before natting companies would purchase entire blocks of IP addresses. Then one day we realized we were running out and we started using NAT. Now it's hard to purchase an entire block of addresses. The military and some big corporations use class A address blocks. You can get over ...

As others have already said, you need to rely on an external service. I'd recommend http://www.exip.org
You can use http://api.exip.org?call=ip to get the ip in plain text format. It's fast and reliable, plus it supports ipv6.

I think I solved the problem. Unfortunately, I don't know which of the two things I did solved it.
First I added one more interface from a different subnet (10.10.8.51), changed the NAT server IP address (10.10.8.200) and sent all the default traffic through that interface.
Secondly, I discovered that the NAT server did ICMP redirect so I disabled the ...

I have the same network connectivity problem upon first startup of the vmimage (i.e. the network appearing OK on both host and vmware image). I close down the vmware image, close down vmware, restart the router, restart vmware, restart the image, and it's back on the network.

These are fake repeaters. Real repeaters require WDS to be configured at the access point. They do a form of NAT that impersonates their clients to the access point. This means seamless roaming is not possible.
The WiFi specification prohibits access points from transmitting data that is not being sent to one of their clients (unless WDS is enabled in the ...
