Anyone build a dmz with 2 different firewalls? (BM3.7 and ISA)
Is this even possible? Also, the external fw will have a public
address
and private address from the DMZ or the internal LAN address? (using
10.0
for the dmz and 172. for the internal LAN) And the internal FW will
have a
dmz address as well and a internal LAN address? Is this correct?

layout:
10.0 - DMZ
192. - private secure devices(vpn,fw)
172. - LAN
