Is it absolutely necessary to use IP-Masq / NAT in order to setup Linux 
as a Router?

 I'm trying to setup a few Linux machines (Centos of course) as 
convential routers as opposed to Gateways so that I can learn more about 
routing between them on various Subnets. 

All the How-To's I've found talk about Masq, I would appreciate if 
anyone can point me in the direction of a convential Linux router howto.

Thanks in advance
