Done. I tried to connect on port 443 but still got no response. Is your
host still up now? It doesn't look like that.
This problem might be easier to debug while talking over IRC, Jabber or
something like that. I'll go to sleep soon... If you have Jabber you can

^^^^^
There it is. You can pass -n to iptables to only see port numbers and IP
addresses instead of service names (looked up from /etc/services) and
resolved host names.
