I have dual firewalls on either end of my DMZ and would like for my DMZ hosts to serve up content to both internal and public users. My issue is that I'm not sure how to simplify the routing.
I have my DMZ host with a default gateway of the public firewall (192.168.2.1, per the diagram) which allows it to serve up pages externally. I am currently using static routes defined on the DMZ host (ie. route 192.168.1.0/24 has a gateway of 192.168.2.251) which works fine. I'd like to do away with static routes and have the public firewall reroute the traffic. Traffic from the DMZ host to the internal network should, in my mind, travel:
DMZ Host (192.168.2.10)
Default Gateway (192.168.2.1 / public firewall)
Inside firewall (192.168.2.251)
Inside host (192.168.1.x)
How do I go about setting this up?
