| old thread, but still maybe usefull:
it's usually most convenient to hookup the airport (or any another wifi-statoin) to your lan, without anything like NAT or DHCP enabled.
usually the cable/adsl modem is already doing DHCP and NAT, so there's no reason to put another layer on top...
this way the wifi-station is just repeating the existing network, as if it were a hub/switch |
