I have a set up in which 2 HP servers are connected to netscreen firewall via an L2 switches. So as per the design, heartbeat probes are to be initiated from the Server1 goes to the layer 2 switch1 and from there needs to go to the layer 2 switch2 and from there communicates with Server2.
These HB probes are to exchange over the Multicast range. So, for this do i need to enable the multicasting on the firewall (L3 interface) or on the L2 interface i can pass the traffic if the servers are in same vlans.
Thanks!
