      Hi Guys,

      I have a strange anomaly using HAProxy : one LAN IP, one primary front end and 2 secondary front ends [all with their own backends]. After disconnecting my router from WAN I still can see traffic on LAN basically pinging my internal IPs.
      It causes a few problems … I can see on my web sites requests to port 80, 443 without real clients.

      Any idea why its happening ?

      Thanks.

        you enabled health checks for your backends. default is a http-check every second.

          Create 2 firewall rule to block trafic on interface LAN for IPv4 TCP destination: Firewall itself destination port 1: HTTP and duplicate it to second rule and change to destination port 1: HTTPS. This is easy like a charm
