Selecting SSH in that router is just a pre-fabbed rule to open the default SSH port 22, if you wanted more PC's running SSHD then you would use different ports. Check to see if the router lets you do a manual port forward, as it should. Meaning you tell it what port to open, not have it tell you.
HMMM. HMMM.
The way I read gumb's description the remote router (?firewall?) is 'pathetic' = 'primitive', in that it does port forwarding only. It may only be a NAT'ing router. Yes, many low end devices are like that. Its typical of ISP economics. (Think of it as pure IPTables setting.)
A more sophisticated firewall/router, say a Linux box running it all, would have a SSHD on the firewall that can either redirect or use as a proxy/forwarder.
Since this is dumb forwarding using the router the more sophisticated binding capability of the ssh/sshd pairing isn't there.
So the ssh connection comes in on port 22 of the Internet side and out to whatever port and address on the inside. Think of this as simlpl pass-though, ore perhaps non-trivial pass-though if its a NAT'ing router that is buggering around with packet headers.
There's a big thread about this router here: https://community.plus.net/t5/Tech-Help-Software-Hardware-etc/Unlocking-the-... I'm not good at multitasking and have been too busy pondering over this ML's responses and typing replies to look into it, so I'm not yet past page 1. But the initial post suggests it is limited. Whilst I can't say for certain without logging into the remote router, from what I recall, it was only possible to assign ONE device on the local network to the SSH service. If you try to add another configuration it says you've already set it, and I didn't see a way to add multiple devices under the SSH service. So I think Anton's description might be the more accurate. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
