I would say it's either a firewall blocking you, or an ACL on a router.

Subject: Cannot SSH from outside LAN


I have an OpenSSH server running on Windows 2000, my router forwarding
from port 8000 to the SSH server.  When I am on my local LAN, I am able
to connect to the SSH server (even on the external IP address, and
external port), but when I try to connect from a machine outside of my
local LAN, it hangs.  Here is sample output from it hanging:
****
:~> ssh 12.210.8.XXX -p 8000 -l sundog -vvv OpenSSH_3.7.1p1, SSH
protocols 1.5/2.0, OpenSSL 0.9.6g 9 Aug 2002
debug1: Reading configuration data /etc/ssh/ssh_config
debug2: ssh_connect: needpriv 0
debug1: Connecting to 12.210.8.XXX [12.210.8.XXX] port 8000.
debug1: connect to address 12.210.8.XXX port 8000: Connection timed out
ssh: connect to host 12.210.8.XXX port 8000: Connection timed out
****
If I connect from within the local lan it connects:
****
$ssh 12.210.8.XXX -p 8000 -l sundog -vvv OpenSSH_3.6.1p1+CAN-2004-0175,
SSH protocols 1.5/2.0, OpenSSL 0x0090702f
debug1: Reading configuration data /etc/ssh_config
debug1: Rhosts Authentication disabled, originating port will not be
trusted.
debug2: ssh_connect: needpriv 0
debug1: Connecting to 12.210.8.XXX [12.210.8.XXX] port 8000.
debug1: Connection established.

Please advise!
Thanks,
Nick
