I'm having a really weird issue with my server (FC6)
Whenever I try to make a request outbound on port 80 to an external server, I get re-routed to myself, and it returns index.html of my own server. What's even odder is that wget report the correct IP address and everything, but sure enough the page it just got was my own homepage.
It's not the router/gateway, as it works fine on a different machine behind the same gateway, and it doesn't apply to other ports. (eg. I can ssh to another host on port 22 or otherwise)
Here's what the wget looks like
# wget google.com
Resolving google.com... 188.8.131.52, 184.108.40.206, 220.127.116.11

Clearly it isn't being downloaded at 59MB/s, but it's getting it's own server's page.
I'm using lighttpd.
Here are the if's on the server.
