Changes

Layer 3 load balancing is implemented as a firewall port forward, which is very efficient, and therefore gives layer 3 load balancing a performance advantage over layer 4+. Because of its implementation, it '''requires the firewall to be started''' (simply check if there are any firewall rules in the configuration). Also because if this, it's normally not necessary to add any additional firewall rules. Further, it's necessary that the load balancer is the default route (gateway) of the servers being load balanced, since the source packets of the incoming traffic is maintained. In order words, the topology would look something like:

Internet -> Halon -> Switch -> Server2

To add a layer 3 load balancer, follow these steps
