To monitor internet link, behind local router pool members, create a icmp monitor with alias address an external IP address (ex : 8.8.8.8) and transparent enabled.

 

For each pool member, it will request ARP of pool member (ex: result 00:01:02:03:04:05) and send a icmp packet with

 

  • destination address 8.8.8.8
  • destination MAC 00:01:02:03:04:05
  • source address the IP address on same subnet than pool member

If no response, the pool is marked down
