SSH Problem

[Nestrus]

Hallo,

ich hab unter der IP 194.208.223.90 einen Debian-Server, auf dem auch SSH läuft.
Aus dem lokalem Netz komme ich (auch mit der öffentlichen IP) ohne Probleme auf den Server aber nicht aus dem Internet.
Eigentlich müssten alle Ports korrekt weitergeleitet sein, nmap liefert nämlich:

Starting nmap 3.75 ( http://www.insecure.org/nmap/ ) at 2005-06-28 18:51 UTC
Interesting ports on 194-208-223-090.TELE.NET (194.208.223.90):
(The 1649 ports scanned but not shown below are in state: closed)
PORT     STATE    SERVICE
20/tcp   filtered ftp-data
21/tcp   filtered ftp
22/tcp   open     ssh
25/tcp   filtered smtp
80/tcp   open     http
110/tcp  filtered pop3
137/tcp  filtered netbios-ns
138/tcp  filtered netbios-dgm
139/tcp  filtered netbios-ssn
143/tcp  filtered imap
443/tcp  filtered https
465/tcp  filtered smtps
993/tcp  filtered imaps
8080/tcp open     http-proxy

Ich weiß einfach nicht warum ich nicht drauf komm...

Meine sshd_config:
