I tried the same thing - setting up a webserver (port 80) and SSH (port 22) without success. I used the NAT, --> Virtual Server section, added the ports like this. I matched up my server IP (show below) and tried both. I did discover that when you ssh over the internet, you get the router's ssh (which I was able to login to using admin/pw). So, the device seems to want to us port 22. So, I tried setting up ssh on port 2222. No luck. Then Management, --> Access Control: I made all was enabled, changed the ports to match, etc. Still no luck.
Has anyone figured this out?
