I have a use case where I would like to route an external WAN Public Address to my IpFire for URL filteering/AV scan/etc. The objective is to somehow put this in line with the internet. I have no problems at all internally on my LAN/WAN setup, but just this one thing I am trying to do.
Red0 is on DHCP on passthrough from ISP modem.
Green0 routes to the private side of my LAN
Orange0 DMZ is not installed.
Has anyone hairpinned traffic from the outside like this through this firewall? If so, would you care to advise or share documentation?
