It's not the basic "look up the IP number" part as that's working just fine. You don't seem to be using their (dynDNS) web redirection service (ie. howse.homeunix.net resolves to 66.168.145.25 which whois reports belongs to Charter Communications). I think that dynDNS would seem to have managed to pull off their datacenter move without much noticable fallout. That's pretty impressive... If Charter are denying any interference with the port 80 traffic at all, then they are almost certainly correct. I think you've established that your FreeBSD box is working correctly. So, I guess, by a process of elimination you might have a problem with your cable router/modem? Is this a device that has a HTTP interface that you can configure it with? -- since it seems to be working perfectly well for all of the other ports, there must be some reason for it to do nasty things specifically to the port 80 stuff. It certainly is perplexing.
