[Devil-Linux-discuss] PLEASE HELP VERY URGENT!!! SOS

[pes c. <pe...@gm...>]

let me explain you the situation first
we have a static IP from our internet service provider ok
our router is a ADSL router with wifi and dmz capabilities
it has 4 ethernet ports and wifi access
i have successfully installed devil linux (Firewall) after the router with
two NIC
first NIC same subnet as that of LAN (ethernet)  of ADSL router . it is DHCP
client of ADSL router.


Second subnet is a class B network for local LAN
i have considered 172.0.0.10/255.255.0.0 as gateway address ie., for second
NIC and also it provides DHCP server for all the client on the LAN  from the
same


NOW we have dedicated DMZ server which was earlier connected directly to
ADSL router
BUT now we want it to be in LAN as well
please let me know how to configure third NIC which subnet it should have

1)WHAT SUBNET should i have for 3rd NIC on DL firewall ?  172 network or 192
one (i assume as class b or class c)


2)can we have a virtual ip for DMZ server that is having both the network
(suppose 172.0.0.254/255.255.0.0 and like 192.168.2.254/255.255.255.0) on
the onboard ethernet card



let this be aside please tell me how to route a DMZ request that comes from
outside (INTERNET) to ADSL router and NAT to this dmz server
