This is obviously a bit of a stab in the dark, but:
1. logs - apache, firehol/iptables
2. packet sniffing - tethereal is your friend
3. check your routing entries - maybe packets are coming in, but the
system doesn't know how to send them back out - this is a wild guess
seeing your email is working
First I would sniff your interface on the apache box and see what it's
seeing. Then divide and conquer from there.

This bit's easy. You can:
1. use a proxying service - I use megaproxy.com, but only cause it was
easy to find. They limit you after a while, so you might want to have a
few such sites up your sleeve, or pay them. Go to their website and
type in the URL and it will fetch it and display it.
2. get a shell account on another machine and use elinks, wget etc. I
thoroughly recommend bur.st - you can get a limited free shell, or for a
one-off donation, get more. Nice guys, good service. There are other
3. find a trusted friend with a publicly accessible box, and get them to
set up HTTP proxying on some port on the loopback. You can ssh into
that, with port redirection, and set up your browser to use that as a proxy

though, yell out.
