Web Server Problem (KFWS)

[wraith112]

Ok first off I'm using Windows XP Home edition Service Pack 2.
I'm trying to host the Key Focus Web Server on my home computer.
I can connect to the server through my lan, but outside users can't.
The server is hosted on 192.168.1.101
My router's IP address is 192.168.1.1
Another computer on my home network is 192.168.1.100
My external IP is xx.xx.xx.xx
When outside users type in my external IP address (70.xx.27.xx) into their browsers they can't load the page.
Now I've read that one reason they may not be able to connect is that my router (Linksys WRT54g) is not forwarding port 80 (HTTP) to my server (192.168.1.101). So I went into my routers settings and forwarded what I thought were the proper ports, and it still doesn't work.

Here are my router settings. Is something wrong with them?

Can anyone lend any insight as to the source of my problem?

Do I have to buy a domain name, or can I use my external IP address provided by my ISP.

You don't need to buy a domain name unless you want it. All a domain name will do is point www.domainname.com to your external IP address (effectively adding 1 more layer to possible problems). Your config shows port 80 listed twice. Try disabling one of those forwards and try again.
