I have an openssh-server running on my computer. However, I'm not able to connect to it from outside my LAN.
Connecting from within LAN is no problem at all, it works just as one would expect. However I get a "connection timed out"-message when trying to connect from outside LAN.
I've already port-forwarded port 22 in my router, so this is not the issue. This problem arose after me having reinstalled my computer. Before this, I had no issues.
Is it a firewall issue in Ubuntu 11.10? How do I solve this?
EDIT: I also noticed that this issue isn't limited to port 22, but all ports.
