Cluster With Advanced Networking is Not Replicating Correctly
VCS Expressways with Advanced Networking are only designed to replicate through their LAN 1 interface. Ensure
that the Peer N address entries specified in System > Clustering all refer to LAN 1 interfaces.
that the Peer N address entries specified in System > Clustering all refer to LAN 1 interfaces.
Also, this replicating interface (LAN 1) must not have NAT enabled on it.
Cluster With Static NAT is Not Replicating Correctly
When using 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 N address entries
specified in System > Clustering must all refer to LAN 1 interfaces. LAN interface 2 must be configured for static
NAT.
