httpd puzzlement

[Ed Ahlsen-Girard]

httpd doesn't serve pages on my Dec24 snapshot system (hasn't ever,
actually).

I am missing something really obvious. httpd exits logging thusly:

Dec 27 10:05:07 $hostname httpd[28709]: fatal: send server: Can't assign
requested address

rc.conf.local and httpd.conf files are below. httpd.conf sets
$ext_addr to "egress", but I do not know where egress is defined, or if
I should replace it. Replacing it with the address bound to the
(single) interface did not change anything.

The box uses dhcp but has a reservation: address is always the
same.
