Pix with 6 Interfaces

Hi everyone,

I would like to know, if anybody has a Cisco URL, for how configure a Pix Firewall with 6 interfaces (inside, outside,dmz1, dmz2, dmz3, dmz4) without nat.

Thanks in advance.

Re: Pix with 6 Interfaces

well, I am using a cisco PIX with 6 interface and without NAT.

First you have to decide upon security level of your interfaces. The Highest the security level, the more protected.

nameif ethernet0 inside security100

nameif ethernet0 outside security10

nameif ethernet0 outside security20


nameif ethernet0 outside security30

if two interfaces have the same security level, they can not communicate.

There are two ways to avoid NAT:

1) use nat 0 with access-list any to any

nat 0 access-list ALL

access-list ALL permit ip any any

(or a moree specific access-list like fron inside ip's to dmz1, outside etc)...

2) use static commands

static (inside,outside) netmask 0 0

static (inside,dmz1) netmask 0 0

static (inside,dmz1) netmask 0 0

static (dmz1,outside) netmask 0 0

need to do static for all interfaces from high security priority to low security priority that you need access to or from...

Try this on for size...

The 'Configuration Examples' should give you an idea about how to configure the PIX.
