Re: [PCTECH] Networking via router?

How many ports on the router? If only 2 (one from the DSL or cable modem, 
the other to whatever), then the answer is no, until you put another device 
on that 2nd port - a router or switch. Many of the SOHO equipment (LinkSys, 
e.g.) can be set up as switch or router - a router creates a different 
subnet, a switch does not. Your first router can probably do DHCP, maybe, 
for you internal network.

If you are on Win 98, it is almost impossible to block access to anything. 
There might be software to do the job. Otherwise, get 2K or XP - I know...

AFAIK, a firewall PC needs 2 network cards - one connected to the outside 
and one to the inside. Think of it as an extension of the inside of your 
router next to the DSL/cable modem.

Without IPCop--

Internet <----> Modem <---> Router (gateway) <---> internal network

With IPCop--

Internet <----> Modem <---> - IPCop (NIC 1) - IPCop (NIC 2) <---> Router 
(gateway) <---> internal network

Someone please correct any deficiencies here on my part.
