[Fwbuilder-discussion] Firewall problem

[Alejandro K. <ale...@ya...>]

Dear all, I have a problem since two days. I have a firewall with a DMZ
and LAN. In the DMZ I have a mail server, I made NAT and filtering rule
for accesing to/from it from/to Internet. But it doesn't work....


Firewall public interface has three virtual addresses (public IP's):
FW:eth0:ip for LAN masquerading, FW:eth0:ip-1 for the incoming/outgoing
mail server traffic and FW:eth0:ip-2 for the incomig/outgoing web server
traffic)

These are the NAT rules:

Any --- FW:eth0:ip-1 --- Any --- Original --- Mail Server

Mail Server --- Any --- Any --- FW:eth0:ip-1 --- Original


and these are the filtering rules:

Any --- Mail Server --- Any --- Accept

Mail Server --- Any --- Any --- Accept

I build my script considering that Firewall is NOT part of any.


Can you give me any help on this ??? If I consider that Any=Internet, is
it OK that firewall is not part of any  ???

Thanks a lot, really !!!



Alejandro
