ProxySG High Availability/Failover fails between Proxies located in different networks

Issue/Introduction
Proxy Failover is configured on multiple ProxySGs that are located in different subnets. They fail to establish or maintain Failover membership.
Resolution
There are two likely reasons Proxy Failover in this scenario might fail:
1. ProxySG requires multicast traffic to flow from one unit to the other. Many networks don't propagate multicast traffic across different networks.
2. The Virtual IP (VIP) used for Failover must belong to an active network. If the VIP has been configured for a network that these proxies are not members of, traffic from one proxy to the other will not be routed correctly.
