Redhat 8.0 networking/routing/security issue...

["nokio x0" <xj3wlzx () hotmail com>]

Hi, i'm not sure if this is the right mailing list to post to or not. But 
i'm sure I will soon find out...

Anyway. I'm fairly new with Linux networking and i'm a little stumped. I 
have three boxes, none have OS's yet, but i'm planning on one having Windows 
XP Pro, and the other two with Redhat 8.0. My plan is to have one of the 
Redhat boxes set up kind of as a router(?) so my two computers other 
computers could share the same internet. Is this possible? and if so how 
would I go about doing this? Also how would I go about securing the redhat 
box for this kind of configuration? I have a cable modem with Comcast @home 
internet. I'm not sure how to configure this under the Linux environment. I 
have contacted Comcast but their support told me that I cannot use their 
internet service with Linux but I have heard from many other network gurus 
that they are full of it and it is totally possible. Any help would be much 
appreciated. Thanks in advance...

Thanks,
nokio
