>If you are setting up your Linux PC as a PPP server, you must compile in

IP forwarding support. This is also necessary if you want to use Linux

to link to LANs together or your LAN to the Internet.</P

>If you are linking a LAN to the Internet (or linking together two LANs), you
|

should be concerned about security. Adding support for IP fire walls to
|
|
the kernel is probably a MUST!</P

LAN that uses any of the above mentioned 'unconnected' IP network
