Servers behind the firewall

[Bernardo Betusi <bbetusi@hotmail.com>]

I have a Linux Firewal (ipchains) Kernel 2.2.16, that has to protect a mail 
server and a web server. I^Òm instaling three network cards.

The first one 1.2.3.4/255.255.255.240 is connected to the router (Internet).

The second one 1.2.3.15/255.255.255.240 has as destination the network in 
which the web, mail and DNS servers are located.

The third one 192.168.1.1/255.255.255.0 work as a proxy (Masquerade + Squid) 
for the internal network.

This particular pair implies that both interfaces are part of network 
1.2.3.96/28 (1.2.3.x ere in fact valid internet addresses)

The router used to access Internet is 1.2.3.3/255.255.255.240

¿How should I do to put the servers behind the firewall?

Thanks in advance. Regards,
