Ben,
I read your disclaimer and fully understand the busy/grouchy thing.  So, if you
don't feel like branching to IP Aliasing at the moment, please use the Del key.

I recently upgraded to FreeBSD 2.2.6 and lost the ability to ping an aliased
address from the box on which it is aliased.  From the outside yes.  It worked
before the upgrade.
I don't particularly wish to add routes during boot and wish to understand why
it has ceased working.

rc.local entries are:
echo -n ' address aliases'

ifconfig ep0 209.113.58.2 netmask 0xffffffff alias
ifconfig ep0 209.113.58.3 netmask 0xffffffff alias
.
.
.
ifconfig ep0 209.113.58.72 netmask 0xffffffff alias
ifconfig ep0 209.113.58.73 netmask 0xffffffff alias

and netstat results follow
TripleCrown:/etc/#netstat -nr
Routing tables
