I want to set up a 3CX PBX in a DMZ.
WAN - DHCP from ISP
The 3CX box is 10.1.1.1. Connected directly to the NIC on the PfSense Box.
To start with I cloned the default "LAN to ANY" rule and changed it to the DMZ1 interface.
3CX has a built in firewall checker, and with the rules below, it passes.
At this point though, this seems to completely defeat the purpose of having a DMZ with the "DMZ to Any" rule.
What should my rules actually look like?
