AFAICT, one must use a netmask appropriate to the network on which the
hme0: flags=8a63<UP,BROADCAST,NOTRAILERS,RUNNING,ALLMULTI,SIMPLEX,MULTICAST> mtu 1500
media: Ethernet autoselect (100baseTX full-duplex)
# Internal (house) network. /24. That's all I need, and NATing anything
# else is just insane.
inet 10.11.11.11 netmask 0xffffff00 broadcast 10.11.11.255
# External real-world address for www, ftp, etc. /29 (8 addrs)
inet alias 220.127.116.11 netmask 0xfffffff8 broadcast 18.104.22.168
# NAT address to the outside world (this is my NAT box), also /29
# since it's within the same address space as the above.
inet alias 22.214.171.124 netmask 0xfffffff8 broadcast 126.96.36.199
