3 NICs or minimum of 2 NICs - pros and cons?
I'm in the process of building a pfSense firewall/router and I was wondering about the pros and cons of using 3 NICs or 2 NICs. pfSense requires a minimum of 2 ethernet ports but since I have an Intel PRO/1000MT (single port NIC) and an Intel PRO/100+ dual port NIC I have the option of using 3 ports if it is advantages now or in the future. Any ideas or options are welcome.

Depends on your network and your desires. Could use a second Internet connection, or setup a DMZ if you have publicly-reachable hosts, or setup a second LAN if you have a need to isolate devices.
cmb: Thank you for the reply.
I plan on using the pfSense firewall for a home network (hardwired) with no DMZ. If I can add the 3rd ethernet port later, I can have a have a separate wifi LAN for my friends with their fancy "smart" toys (crackberry, iPad, etc) when they come visiting but only later as I need to get comfortable with the pfsense first.
As a newbie here's the stupid question: Is it possible to start out with the 2 NIC configuration and later on expand to the 3 NIC configuration for a separate LAN? In which case, should I just plan on installing the 3 ports and not use/configure the 3rd port now?

Yes. If you already have the three ports now it might be more convenient to install them now - it would save opening the box later. It is not necessary to configure pfSense to use all the available NICs and it is not necessary to enable all the configured NICs.
Thanks wallabybob and cmb.
That's one problem down and a couple more to go.

I have only one WAN and one LAN with LAN Subset 192.168.2.0/24 and 3 PCs on this LAN.
