I'm having an issue with opening my SSH port. Here are the symptoms.
Within the local network I can ssh to the machine, including both locally (ssh localhost) and from alternate computers.
I have correctly port forwarded the incoming connections to the LAN IP.
On the local machine I can nmap the LAN IP address and see port 22 open. I can also nmap the WAN IP address and see port 22 open, along with other services on the router.
I can ssh the WAN IP from the local machine.
However -
From external machines, I cannot see port 22 as open (examined via nmap)
Sites such as can you see me are reporting port 22 is closed (connection timeout) from the local computer.
I'm running Ubuntu 11.10, and do not have any intermediate firewalls present.
Any ideas would be greatly appreciated.

&2222
, have you checked reports of that being the case for yours? Have you tried enabling another service to see if that works (easiest is probably Apache2 on80
or8080
)? I know you said that you have the forwarding correct, but that would make sure other types of services work and it's specific to 22.
