I have an Ubuntu 14.04.1 LTS (GNU/Linux 3.13.0-45-generic x86_64) installation which I want to use from an external IP address via SSH. The ip number is 192.168.0.58, SSH port is 22.
I have a Ziggo Ubee modem, which allows SSH forwarding with external IP 84.x.y.z. I have configured port forwarding at this modem for port 13358 to ip 192.168.0.58, port 22.
With my laptop I can reach the machine via SSH in two ways:
1. If my laptop is in the same network and use SSH to 192.168.0.58 port 22
2. If my laptop is in the same network and use SSH to 84.x.y.z port 13358
If I place my laptop in the network of my neighbour (with allowance and via Wifi), and try to connect to 84.x.y.z port 13358 I get a Connectoin Timeout. If I use another external network, I get the same error.
Some months before I used the same construction for another machine, which worked very well.
I can use SSH from my laptop to another external IP address.
I have already reset the cable modem, resetted it back to factory configuration, but it didn't help. I tried with the server configured as DMZ and 'not as DMZ'.
HELP! Where can I look further to solve this? Could it be some exotic ssh-parameter?
