[NTLUG:Discuss] use linux box with 3 NICs

[Michael H. Collins]

I would set up the floppyfw with 3 nics.  http://www.zelow.no

The firewall.ini in floppyfw is a good place to start learning 
firewalling.  The box will have no services running and is almost 
impossible to penetrate.

Those linksys routers are trivial to hack.  The new LJ has a great 
security article in it.

Have fun
