Title: Transparent firewall: What is use case and approbriate setup?
Post by: cmonty14 on December 18, 2021, 12:10:53 pm

Hello,

my ISP offers me 1 static public IP (not more).
I want to use this static public IP with multiple services, e.g. private cloud, mail-server, etc.

In a traditional setup I would configure a DMZ for these service. In addition there's a forward proxy in this DMZ to "route" traffic for cloud.mydomain.com, mail.mydomain.com, etc. to the relevant server.

Question:
Is the setup of a  Transparent Firewall (https://docs.opnsense.org/manual/how-tos/transparent_bridge.html) working for these conditions / restrictions?

THX

I would never put my devices which are normally in a DMZ, in my the same subnet with the rest.

Actually I could setup a transparent firewall with a bridge on interfaces DMZ and WAN.
