ssh connection refused for external IP's


I've searched around the forums here and can't find an answer to my particular problem: ssh connects to my linux box from anywhere in the local network (192.168.0.*), but fails from any external IP.

I've put a clean install of Mandrake 10.1 on my linux box. Security level is set to Higher. I've temporarily turned off the firewall. My hosts.allow file is
sshd: ALL
My hosts.deny is
ALL:ALL EXCEPT 127.0.0.1:DENY

Port forwarding on the switcher to the linux box is working.

Error from ssh on the external machine trying to connect to my linux box (I've sensored my IP):
ssh -v [x.x.x.x]
OpenSSH_3.6.1p2, SSH protocols 1.5/2.0, OpenSSL 0x0090701f
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug1: Rhosts Authentication disabled, originating port will not be trusted.
debug1: Connecting to [x.x.x.x] port 22.
debug1: connect to address [x.x.x.x] port 22: Connection refused
ssh: connect to host [x.x.x.x] port 22: Connection refused

Any advice?

Do you have any firewall rules in place on the router?

What about the linux box?
iptables -nL

The linux firewall was disabled (via drakconf, etal.). The hardware switch is forwarding the proper ports correctly.

I found the problem: the DNS from the external site was not working. It was not looking up my domain name properly. Doh! Once that was fixed, no further problems.
