OpenSSH Port Triggering?

[Dewey]

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.

Thanks.

Does your router support forwarding ports to a range of IP addresses?? As far as I know most routers for home use will only forward a port to only 1 LAN ip address.

If you problem is that your computers occasionally change IP addresses than I would recommend setting leases on IP's to expire after a certain amont of time (eg 24hours) that way no matter how many times you restart that PC it will always get the same IP address (providing the lease hasnt expired)

You should also be able to specify through dhcp which host is allocated a certain IP address (these are normally linked to MAC address in router based dhcp)

No, it doesn't support forwarding to a range. I wanted to use port triggering for this reason, because it worked fine with Webmin, which was using:

Name: Webmin Trigger port range: 10000 ~ 10000
