comment Although 80 and 443 are system ports, how are most web servers able to bind to them anyway?
and just to clarify for OP: the reason that option #1 works is because when processes drop privileges, they're allowed to retain open file descriptors - even if they wouldn't be allowed to open them a second time.

comment Ping and traceroute can resolve my IP, but real clients (Apache, Adium, ssh) cannot
Weird, the issue happened all the way up until I asked this question, and then it automagically started working. Probably I invalidated a cache or something in diagnostics, so I think the DNS cache was the culprit.

@SanderSteffann because when I enter the direct IPv4 address into the client, it works. My assumption was that the client was trying to use IPv6 and failing, but I have no way to further narrow the device causing the protocol mismatch, or even to confirm that that's what's happening.
