When using Cisco VCS Expressways with static NAT the cluster replication must occur on the LAN
interface which is not behind the NAT device. Therefore LAN interface 1 must be the non NAT
interface and the Peer x IP Address entries specified in VCS configuration > Clustering must all
refer to LAN 1 interfaces. LAN interface 2 must be configured for static NAT.
