I've been trying to setup SSHD to accept outside SSH connections by using port triggering, but it always times out.
I have a network everywhere 4port router. I tried setting up triggering with
Name: SSHD Trigger Port Range: 22~22 Incoming Port Range: 22~22
but the connection times out.
However, when I use port forwarding with my router, I can connect from outside my lan using the settings:
Name: SSHD Ext. Port: 22 TCP Int Port: 22 IP: 192.168.1.101
Now, while this works, I reboot the computers on my network occasionally, which messes up the port forwarding, because all my IPs are distributed via DHCP. So if I power on the computers in another order, the port forwarding points to another computer. So what my question is, how do I get port triggering to work for SSH, I suspect that the trigger port range is wrong. I've checked linux google, and the openssh docs, but didn't find any relevant information.
