Hallo
Leider ist mein Deutsch nicht besonders gut, deshalb schreibe ich auf Englisch.
I have a (Linux) computer connected to my Vodafone router via ethernet, and I would like to be able to access this computer remotely (i.e. when I am away from home). I am trying to solve this via port-forwarding (admittedly I am still a novice with networking). I couldn't find port-forwarding on the "Vodafone Station" though I did find IPv6 Host Exposure, which seems to be what I'm looking for. I added the device there, gave it a Port and TCP/UDP protocal. I also made sure to give it a static DHCP (Einstellungen -> LAN -> Statisches DHCP - Heimnetzwerk).
When I'm on the network I can connect to it just fine via `ssh <user>@<local_ip_address>` or (after editing `/etc/ssh/sshd_config`) `ssh -p <port> <user>@<local_ip_address>`. However, I cannot connect outside the network, even with the host exposure. I got my router IP from: https://www.whatismyip.com/ then tried `ssh -p <port> <user>@<router_ip>` but I get the error `Connection refused`. Are there any instructions on how to properly set up remote access for Vodafone routers?
