Hello, I have a NetBSD 1.4 machine that has two NICs. 

We have a DSL line coming into our place and I'd like to hook it up the
BSD box to get my other two computers online.
 
I don't have the numbers with me, but lets say the ISP gave me the
following info:
 
IP address: 1.2.3.4 (ok, i know...i'm just making this up)
netmask: 255.255.255.252 (i remember that one)
router: 1.2.3.5 (also made up)

OK, so I plug the DSL line into one NIC on the BSD box. I plug an ethernet
cable into the other NIC and hook that up to the hub. 
 
What do I need to do to rc.conf, hosts, ifconfig.ae(1/0), ipnat.conf, etc?
 
My LAN is using 192.168.2.x as its addresses, with 192.168.2.1 as the NAT
box. 
 
Any help appreciated; extra explanation of the concepts involved here also
very appreciated :)
