How are you suppose to NAT with snow leopard server mini with only 1 ethernet port?

How are you suppose to NAT with snow leopard server mini with only 1 ethernet port?

From serverfault erotsppa

• You can use NAT with Ethernet and AirPort.

  Tom O'Connor : Ugh. Servers on WiFi.. That's just destined to fail.
  From Cheeky Modge

• Set up 2 or more VLANs on the ethernet port.
  Use a managed switch to break these VLANs out onto physical ports. That way, you could have non-nat traffic on VLAN 2, and natted private RFC1918 traffic on VLAN 3, all shared on the same physical ethernet port.

  Gotta love 802.11q...

  From Tom O'Connor

• Use NAT to bridge the ethernet access to a FireWire LAN. I've done it ;). Performance isn't great, but you can blame the IPoFW implementation for that.

  From Graham Lee

• Or pick up a USB->Ethernet adapter.
