If you can ssh from your Mac to the external IP address of your router (and it works), but it doesn't work if you try it from a location outside of your house, then it might be blocked by your ISP.i can internally ssh fine and how would i find out if port 22 is blocked
When you goto that website, is the IP addr in the Remote Address box different when you use Ubuntu vs when you use it with OS X?so i have determined that when i use this website from ubuntu it says the port is open but when i use it from os x it says the port is closed port 22
