OK, so just for the record: What does NAT stand for?
fwiw, I'm running macpoet and it seems to be behaving.
I have a client who had been using IPNetRouter on a PPC Mac with DSL connection. When they were forced to change to a PPPoE (evil) connection I tried setting the machine up to use IPNR and a PPPoE client but could never get it to be stable. There was always a problem with connecting when the PPPoE connection dropped. I know I used the other software and I might have tried MacPoet, I don't recall off hand. I ended up putting in a hardware router which handled the PPPoE part okay.
The usual problem with PPPoE clients involve working with IPNR routing software and it's a limitation in the PPPoE client software that is the problem.

I totally missed out on this thread, but maybe I can help here :)
NAT: Network Address Translation
NAT works by mapping IP requests from a private address, thru a public address, and back again. This allows one node (router or computer) to provide a connection to the outside world for the machines within the private network. This also allows for a sort of "firewall", as NAT will only forward port to port (i.e. 110 on router to 110 on mac) if instructed to do so.
OS X has this capability built in via the Sharing control panel. However, I'm with the previous suggestion of using a hardware based solution. It doesn't tax the bus/cpu of the host machine, instead offloading it to a dedicated piece of hardware.
Also the hardware router draws about 1/10 the power so leaving it on all the time isn't a big concern.
The biggest problem I've run into with hardware routers is that I haven't found one that has all the features of IPNR. One I've used couldn't port map from one port to a different port so you couldn't (easily) have multiple servers of the same type behind the router. Most have very limited DHCP. I like to be able use DHCP to issue static IP addresses to specific machines. This is useful for laptops so they can get a static IP at home but connect elsewhere without having to change the configuration any. I'm using a hardware router with on of my servers running IPNR providing DHCP (and MacIP).
