My ISP (Verizon DSL) blocks port 80, thus the need for a port other than 80 to the outside world. The iMac sees it as normal http traffic. Someone wanting to get to my web server needs to use an address with port specificed as 1234 (http://mydomain.com:1234). I'm using no-ip.com's service to, among other things, do a web redirect of www.mydomain.com to mydomain.com:1234 so you don't have to remember the port. No doubt there are better ways to do this, though. I set ServerName to mydomain.com:1234 and that seems to work. I haven't yet tried setting it to mydomain.com (without the port) but I don't think that would work because the request has to be to port 1234. Steve
