Port forwarding on a wireless router.

I have a BT Voyager 2100 router where 3 computers connect to this giving them, .1.3 and .1.4 addresses where the router is .1.1. This router has a web interface for configuration which runs on port 80. I want any web requests on the the routers IP to be forwarded to a Linux box with Apache running on it. So far this has proved a struggle. I have disabled the web interface on the router and added port 80 forwards to (Linux box) but it just doesn't forward. I can access the web server locally but not externally. I've updated to the latest firmware for the router but port forwarding didn't work before of after this firmware update.
Has anyone else had a web server running on a network with a wireless ADSL router with NAT.

Thanx in advance, Ste.

The way I have mine set up, is my Apache webserver is set on a box with DMZ permissions from my router. It's a setup highly similar to yours. I had to actually tell my apache server to listen on port 80 of my ISP's assigned address before I could get anyone to access it outside of my own LAN.

You might want to try in the Network forum; people experienced with port forwarding would pay more attention there.

I never knew that was possible to disable a router's web interface??? I would do not see the purpose of it? how would you be able to configure port forwarding???

How are you trying to access the website externally?
Do you have a website name already registered and reserved? or are you putting the external IP address in a web browser on a computer outside your network?

I have setup a port forward to port 80 on a (Linux box with Apache) but if I access my external IP it goes to the web interface of the router. EG http://84.45.x.x

Still no luck though

I have tried enabling DMZ to the Linux box but it's still not getting there. You mentioned configuring Apache to listen on the IP issued by my ISP? Would this overtake the web service my router runs for configuration? Where in the Apache config file is this defined?



Just to add - I edited /etc/httpd/httpd.conf and changed the listening port to my external IP on port 80 which caused the httpd service to fail while booting so I changed this to run on port 700 so there are no conflicts between apache and my router web interface. This was accessible on port 700 through my local IP (192.x) but not externally. It just doesn't appear. This is all while port forwarding is setup and DMZ both to my Linux server box.
