Setting up an inline DMZ
I've recently purchased several Firebox M200s. One M200 will act as an exterior bastion firewall; the internal firewall will be something else (taking into consideration a defense-in-depth strategy - never use the same firewall architectures between exterior and interior firewalls).
The configuration that I would like to create can be simply shown below:
External Internet >> External DMZ (DMZ-1) >> Internal DMZ (DMZ-2)
23.x.y.0/24 >> 10.1.y.0/24 >> 10.2.y.0/24
Servers will be like for line configuration. In other words, 23.x.y.1 will translate as 10.1.y.1 in the external DMZ, then translate to as 10.2.y.1 within the internal DMZ.
Are there any examples out there that I could use to create something for this simple configuration?
Mucho appreciato (in advance).
