A friend of mine is running win98 machine as a server with XAMPP (apache & mysql) and Joomla CMS.
The live site url is http://##.##.##.## (his ip address provided by isp)

I have set is domain name to point to his ip address provided by ISP and yeah every man and is dog can see his website but my friend can't.
We thought initially that he had a blackhole router but we have changed it to a Netgear dg-834 which I know works perfectly well.  When my friend types his domain name url into his browsers address bar (either IE or MOZILLA) he get the router login screen.
He can see the site if we change the live site url in Xampp to his local ip address 192.168.0.3 but not with the external ip address.
There are no firewalls running to block the sites.... we've also checked the settings in IE & mozilla and I've also gone through his network settings on his xp machine.  Still no joy.

So my question is :
Why can every man and his dog see the website externally but not from within my friends own network ?

Answers on a postcard please.
Your HELP would be most appreciated.  Thank you.

You owe me a dollar for this:  

Some routers assume any web traffic from inside your network that is addressed to the router is intended for the router's own configuration interface. The good news is that people in the "outside world" can reach your site just fine!

link here: http://www.boutell.com/newfaq/creating/firewall.htmlThanks for the info but the netgear isn't one of these routers.  I have one and have never had this PROBLEM.....  so any other ideas would be great.

Mind you I'm starting to think its maybe his provider at fault... he can't even FTP to another site! [shakes head in desperation]

Cheers

Kate, has the new router been configured with its web management interface on a non-standard port (it should, really)?  If he pings his domain name from within the LAN, what IP does it resolve to?
