Hello!

I've looked around in the forums and found several posts
about almost same problem as me. But I can't just fix my
problem with the help you've all give the others. So it would
be really great if I with my bad english could get some help
so that I can understand my own problem.

The thing is that I've recently installed apache webserver 2.2.
It works good when testing with localhost (127.0.0.1) and connecting
to my computer with Lan ip from other computers in the network
(192.168.1.***).

Then there is this problem. My router is set to portforward all
ports to my computer. Because it's only my computer that needs
ports opend. So I've just opened them all to my computer, and
because this didn't work I even put the computer on DMZ.
The problem is as you might have guessed by now, I can't access
my apache web server homepage at my computer from outside
my network (Ip 217.210.200.***).

I've tried to find the problem on my own by searching at google
and asking other people for help. But I just can't find the problem.
I've tried doing everything I can with the router. And I've tried almost
everything with apache server configuration (the things I understand
anyway). I noticed that when I change listen port from 80 to something
else, it doesn't work even on localhost / network or remote.
Is that weard?

Anyway. Please help me solve this problem. If it helps I could
reset the router and reinstall apache so I start from zero.
Thanks for all answeres in advance!

Sounds like your ISP could be blocking servers on port 80, or at least stopping there clients from starting servers. This is common amongst large ISP's to reduce upstream bandwidth.

Resetting the router and starting from scratch is going to waste your time.

Research dynamic dns ( dyndns.org ), it allows people on a dynamic IP to host a server.

I hope this helps.
