I'm using an Apple Airport bridge, and it will act either as a bridge
or as a NAT router.   Unfortunately, it will not act as a non-NAT
router.   It will do DHCP, or not - it's configurable.   The main two
problems with it are:  40-bit card, and won't bridge air-to-air.
Also, it's easiest to configure if you have a Mac running MacOS,
although it's configured through SNMP, and I'm told that there is a
Java SNMP toy that will configure it (but I haven't tried it).
