What you probably need is something like:
iptables -I INPUT -p tcp --dport 22 -j ACCEPT
where INPUT is the name where most of your rules are defined.
That will open the ssh port, which your telnet diagnostic seems to show
isn't connecting.
As for how you save that configuration, you will need a debian expert, I
run fedora.
