I have sbc/yahoo dsl (dynamic ip) and i'm trying to allow ssh connections to a linux box on my lan here at home. i set up ipforwarding on the router to the linux box but when i try to connect i get a connection refused.

sbc doesnt block any ports and when i use http://www.no-ip.com/tools.php to check if a port is open it shows that port 22 is open and all others are not (as it should) If i disable ssh and disable ipforwarding it displays that 22 is not allowing connections (again, as it should). what gives? can anyone suggest some troubleshooting tips to figuring out why i cant connect?

Thanks!
