@juananpc said in HAProxy doesn't resolve on LAN interface:
instead of selecting "any" (IPv4) in the frontend,
What exactly are you trying to proxy? Why would you pick the lan address?? I have to things I run through ha proxy. One frontent directly listens on my wan IP. Other listens on my loopback since I share this port with openvpn 443, and when its not openvpn traffic, openvpn using share port option sends this to the loopback on a port 9443 and haproxy sends that on to the backend.
If I want to access either of these from my lan, I access my wan IP on the ports being used 443 or 44301 and the proxy sends me to the backend.
