home web server help

[peter69]

I am try to setup a webserver on my xp pro machine using WEBXQ. My machine has a IP (169.xxx.xxx.xxx) and my ISP assisgns a dynamic ip for me. They allow a small web space on their server for users, which I use. On that space, I redirect to my home machine IP, which in theory I think should work. It works for me, but when a friend from outside tries it, they gey the message that says it times out, taking to long to respond. I tried this once with IIS, but also got same results. I am a newbie to this, so any help is appreciated.
Thanx in advance

Have you set up IP forwarding so that the public IP maps to the APIPA of the local system?

As i said, I am a newbie. What is APIPA and how is it configured. I dont have a router, just a DSL modem

OK - the 169 IP address is your APIPA address (although I must admit, that not usually normal - I would expect a 192 internal address for an internet connected system but that was what you indicated)

A 169 address is what a system assigns itself when a DHCP server (or applicable IP assigning service) cannot be located.

Generally, a DSL modem will pick up a public IP address - as an example 15.x.x.x and then "behind" it, assign computers a 192.x.x.x address.

For me to access that machine on your internal network I would enter www.<NAME>.com which some DNS server somewhere would direct me to your external 15.x.x.x address. Your DSL modem, if it is correctly configured to forward calls would have a NAT mapping of 15.x.x.x to 192.x.x.x so that I could reach into your private network and access that resourse

This is how it would otherwise work
