Is it possible to use the iptables CLUSTERIP target in a two node router pair?
My testing experience shows that it works perfectly for connections to the hosts but packets addressed to the multicast MAC address with other IP destination addresses will not be picked up and forwarded.
I tried a CLUSTERIP target rule in the PREROUTING chain of the nat table but that has no effect.
The goal would be to load balance outgoing traffic between the uplinks connected to the routers.
Is that even possible?
