Firewall on DSL router - good enough?

[Davor_Balder/FOAMS/PACBRANDS/PACDUN@pacbrands.com.au]

Hi all,

I have recently acquired a router/dsl modem with built-in firewall
(according to manufacturers technical documentation) and am planning to use
it with my Debian box.

I have noticed there is a firewall built in as well as NAT and a few other
bits and pieces.

Google search revealed there are quite a few manufacturers that offer DSL
modems/routers with firewall protocols built in.

>From a practical point of view, how good are these and should I consider
rolling my own firewall?


regards,

davor
