DGND3700 port forwarding
I've just upgraded from an old DGN2000 to the DGND3700 and I cannot get port forwarding working under this new router. I'm running firmware 10.0.0.12_1.0.12 which is the latest.
I'm just trying to get ssh access for a start to an internal PC on the network through port forwarding.
First I've setup a Custom Service under Port Forwarding for SSH with start port 22 & end port 22 and then I put my PC as the server IP address. I have the sshd running and tested on my PC.
I've tried changing some settings in Advanced -> WAN Setup.
NAT Filtering I changed from Secured to Open, no change, even after rebooting the router.
If I toggle the Respond to Ping on Internet Port then from an outside computer I can now ping my external address. So I've tested that the external address is correct and that I can influence something about the router.
I've tried turning on the 'Default DMZ Server' and pointing that to my computer just to see if I can by-pass the firewall.
I've checked to make sure my firewall at the ISP level is off and I know this was working on the old router.
Is there anything special to do with the router stopping me from port forwarding a simple ssh service?

Re: DGND3700 port forwarding
you are not testing behind the route are you? loopback will cause the failure.

Re: DGND3700 port forwarding
I'm always testing from a remote server. First I ssh out of the building to a server, then I try and ssh back in through the outside IP address as stated in the Router status page.

Re: DGND3700 port forwarding
I was ssh in to my office and back out again using the outside IP address mentioned in the Router Status page.
This morning I tried connecting to it via my phone and it worked.
Seems like the new firewall at work is restricting me a little too much.
Problem fixed, thanks.
