SSH issues when connecting from outside LAN

[fedoraguy123]

Hi all
I am new to linux.
I have a fedora core box which is behind a router and I have ssh setup.
I can ssh into this box from any machine in the local network but I can't ssh from the internet into this host eventhough the IPtables rule has been setup and the ports in the in the router have been opened.
Does anybody know what am I missing?

All ports needed are opened and redirected properly on the router.

Is this a store bought router?
Even if it is not if you have the port 22 open and being forwarding to the internal IP and port of the machine and the machine's port is open ( which appears to be since you can connect local ), then it should work.

Things to try.
From the network use one of those post checking sites like http://www.hackerwatch.org/probe/ and scan for port 22 and see if it open.

One thing it can be is the provider you are using is blocking common ports to stop an end user from running a server. Some charge to allow you to have normal access to your own stuff. One way around this is the following. On the router use port 10000 and forwarded it to your internal lan machine port 22.
Ext IP, port 10000 ---> Int IP, port 22
