Access my computer from outside problem


Grr! I am getting confused...

I have a Dlink 624 router and a Powevook G4 alu.

I want some help with settings/config from "outside" and I am trying to let them in to my computer.

1. I open DMZ in my dlink for my computers IP
2. I open the OS X ssh port/option in the filesharing (tried to stop firewall as well)

But still when friends try to ssh to me the message are:
ssh: connect to host port 22: Connection refused
How can port 22 be closed when EVERY THING is opened?? :(

Kör jag en: netstat -na på min PB så ser jag med att port 22 is open

tcp4 0 0 *.22 *.* LISTEN
tcp6 0 0 *.22 *.* LISTEN
Pls. guys,, whats going on here???
