Scenario: Reverse Proxy in a DMZ

Here we would like to give an overview of the necessary ports and protocols for a reverse proxy in a DMZ.

The scenario would be that a reverse proxy is used in a DMZ. The DMZ has a link to the WAN and LAN.

Configuration

• Before you can setup your Firewall you have to read the book Reverse Proxy in the V13 IT Connect Training.
• If you already have used some of the port forwards from the collumn WAN ⇒ DMZ for other Systems you have to combine all forwards in the reverse Proxy or use a separate ip address

WAN ⇒ DMZ (Reverse Proxy)	DMZ (Reverse Proxy) ⇒ inside (PBX)	DMZ (Reverse Proxy) ⇒ inside (Application Platform)	inside ⇒ DMZ (Reverse Proxy)	DMZ (Reverse Proxy) ⇒ WAN
