WNR2000 Port Forwarding Problems

I've got a WNR2000 connected to a cable modem, and two computers on my network, both using 802.11g wireless. The modem is the only thing directly connected to the router.
The issue: I'm trying to do port forwarding of SSH (port 22) to my desktop. I've set a fixed ip for my desktop under the LAN Configuration tab in the rouerlogin.net page, and I've setup port forwarding for TCP only (though I've tried TCP/UDP as well) on ports starting with 22 and ending with 22 for my desktop's ip. I have also set up DynDNS, and when I click check status on that page on the router it says it's ok. I can ssh to my desktop fine from another computer on my home network, but if I attempt to connect to it via my DynDNS address OR by using my current external ip (found on the router current status page) the connection request is blocked or denied. I'm pretty sure it's not my ISP because I had this working on another wireless router before it kicked the bucket.

Any help appreciated!

Thanks

You may need to set the service you created in port forwarding to "never" in block services.

Re: WNR2000 Port Forwarding Problems

Tried that, no dice. I think it must be my computer, apologies for placing it on this forum. I tried connecting from a remote machine to my home ssh server with my home machine turned off, and got a "connection timed out" instead of "Connection refused". Therefore it must be my home computer, somewhere.

Thanks,

Re: WNR2000 Port Forwarding Problems

if you are testing behind the router for external IP or DynDns, it's loopback

make sure all your testing is done externally and not behind same LAN subnets

Ah Ha!!

Many thanks!

I had no idea that some routers allowed loop back and others didn't. My last two did, so I just assumed they all did. Ok, time to take some networking classes...

Thanks again,

Hey! I have been having this exact same problem, but it is not loopback causing it. Any idea what else it could be?
