if your system is secured with iptables, and you are using a DROP policy:

iptables -A INPUT -i eth0 -p tcp --dport 22 -j ACCEPT
iptables -A OUTPUT -i eth0 -p tcp --sport 22 -j ACCEPT

If the firewall on your router is not active, than you will have to open port 22 (sshd) using the above mentioned command.
But first take a look at your iptables rules. It may already be open.

To do that, open a terminal window (console... command line).
To create, modify or remove rules, you have to be root.
Type the following command and enter the root password:
su -
To view your iptables rules, type:
iptables -vL

are you sure the command is 'iptables'?
because i have this :

root>iptable -vL
iptable: Command not found.

root>iptables -vL
iptables: Command not found.

so i don't understand....

thx ;-)

Maybe you don't have it installed. Or maybe you are using ipchains.
Which distro do you use?
