[CLUE-Tech] Subnets

[ian]

So you have a couple of boxes that you want to have full access to the
internet?  Basically.. you have 3 sets of boxes.. 
A, B & C

A = 1 Box - The router / NAT / DHCP 
B = NATted boxes which exist on a private network
C = Boxes that are part of the internet

It goes like this.. Internet -> A -> B & C

You can use your Firewall/Router server to handle both.  
What you need to do is as follows:

1)  Set up your Subnet B as Masqurading through the firewall/A
2)  Setup your Machine IPs (as these are defined by your ISP) to route through A

To do this you need to have a seperate ethernet card for each subnet so A will have to have
3 ethernet cards.

There is a ton of info out there on routing, MASQ (masquarading) and Firewall configuration.
Just look for the Linux Documentation Project and you'll be all set.

Granted this doesn't tell you line for line how to do it.  Its not easy.. Just straight forward
step by step.
