best way to have an external firewall (not simple firewall)

[joe angth <joeangth@yahoo.com>]

hello all, i am trying to set up an external firewall,
and i'm asking the best advice on how to do it.

Network config:

Internet -> ext-fw -> switch -> int-fw -> switch ->
int
                        ->server1
                        ->server2
                        ->etc

My question is this, is it easier/better to have
ext-fw just be a firewalling bridge, or should i play
with the routes and have it actually act like a
router?, ie, pass all packets for everything else
through, and then have it act as a gateway for all the
servers and int network?

-Joe
