Description

HAProxy version: 1.7.11
pfSense version: 2.4.3-RELEASE-p1 (amd64)
built on Thu May 10 15:02:52 CDT 2018
FreeBSD 11.1-RELEASE-p10

I have Port Forward rules that are tested and running. When HAProxy is started (i.e. after configuration FE/BE), all Port Forward rules stop working. All configured ports of the Port Forward rules stops working even within shell. It will only work again when HAProxy package is uninstalled.

I've been able to reproduce it 5x already. It specifically occurs when a new BE is created. Here's further info

My setup has 2 test NATs (forwards to 80/443 on 1 host on the LAN zone). They're perfectly working fine. HAProxy also starts up fine when no BE/FE configured. Everything is in default. But when a new BE is configured which points to the same 1 host:port on the LAN zone, NAT rules suddenly stop working. Rebooting pfsense doesn't do the trick. NAT rules works again only when removing the BE and rebooting pfsense, or when uninstalling haproxy package and then rebooting.

Issue doesn't happen on my production setup with haproxy 1.7.4 on pfsense 2.3.4-Release-p1.
