Are you on ppp or pppoe? When you try to telnet in from outside,
you should be able to do GET / HTTP/1.0 and the server will
respond, but instead the connection closes. This makes me think
that a small connection is working but not for more data, and
maybe path mtu discovery and/or tcp maximum segment size
negotiation are broken because pppoe has an mtu of 1492 instead
of the ethernet mtu of 1500. It might be wrong, but I think being
able to get response headers from the server over telnet from
outside would be the next progress to make in troubleshooting it.
