freebsd security - Dec 2006 - ssh session from external machine

Hello,

I am having a small problem with the ssh daemon on my freebsd box. I am
using the standard ssh daemon asked at the installation. I am able to acces
my box using ssh from the internal lan network but not from any external
machine. The error code is connection refused. I am using release 6.1 and my
modem firewall permits the inbound traffic on port 22. I also use port
forwarding for sending the traffic to port 22 to the correct machine where
the ssh daemon is running. Maybe i am missing any configuration hint or
something else.
Does anyone has any Idea?

The first step I'd take would be to run tcpdump on your internal machine 
to verify that the packets are getting through the firewall, and if the 
internal machine is responding.

That's just troubleshooting 101.

Check your /etc/hosts.allow that you don't have any restrictions there or 
at the least allow sshd connections from the IP of your firewall.  If there 
is nothing preventing the connection on the FreeBSD box, check your 
firewall's docs for configuring ssh access through the firewall.  It may 
need more than just port 22 forwarded.
