Cannot access my website

I'm at the end of my rope here. I have been working for a couple of days (on and off) to try and make my web site available to the WAN. I have been through the setup guide and the wizard a dozen times, to no avail. My home server has three legs to it:

1. VNC server - up and running, totally successful using COTVNC
2. SFTP - no problem; I can upload, download, rsync - you name it. Super sweet.
3. Web site - forget it. Absolutely not. buddin.dyndns.org is not available to the WAN. The error I get says the server is unavailable. I should note that as a proper server, the computer is awake 24/7

I feel like this last component should've been the easiest part. Just so you know, here are some of the things I've made sure to do:

• Cox communications blocks port 80, so I edited the Apache httpd.conf file to listen on ports 80 and 8080
• Restarted apache after making changes
• assigned my server to a static IP on the LAN (192.168.0.6). The server is also running the dyndns updater daemon in the background.
• Configured my router (motorola sgb6580) to forward port 8080 (and port 80; I can't see the website locally if I don't do this) to the server's IP (above)
• Turned off router WAN blocking (not the firewall, though)
• In the process of getting my file server and VNC server up and running, I also forwarded ports 20-22 and 5900 to the server IP. As I noted, these work fine, so port forwarding/incorrect configuration is not my problem.

Like I mentioned, I'm at the end of my rope here. All I want to do is host one web site for our family to see updates, videos, etc., of our new son. Nothing complicated. No need to configure multiple hosts or anything like that.

Any help would be appreciated.
