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

Use vLans. You should consider visiting some of your old questions an marking answers correct if they are. –  Chris S Jun 8 '10 at 20:15
    
Shouldn't it work out of the box?? Apple designed this! –  erotsppa Jun 8 '10 at 20:15

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...

You can use NAT with Ethernet and AirPort.

Ugh. Servers on WiFi.. That's just destined to fail. –  Tom O'Connor Jul 5 '10 at 13:04

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.

Or pick up a USB->Ethernet adapter.

While VLANs are probably the best solution, NAT on a stick (sometimes called 'loopback NAT') works just fine. It doesn't provide the same security as traditional NAT, but most people are using NAT to provide access not to prevent it. Essentially, your inside and outside subnets just live on the same Ethernet segment.
