Apache Running... But the port isn't open.

[James Taylor]

I just installed apache2 through ports, but am having a really bizarre
problem here.  The server starts with no errors, and upon doing a ps
-ax, it looks like it's running just fine.  'lynx localhost' pulls up
the page, everything looks good so far.  Trying to get to the site
remotely - connection refused.  I ran nmap localhost on the server, and
the only thing it's listing as being open is SSH.  Any ideas on what's
going on here???
