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.
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.
