Network Uses Mobility Router Redundancy Cluster Without
NAT
In this network configuration, there is a cluster of two Mobility Routers. Each Mobility Router uses the
eth0 interface for communications to a default gateway and the internal network. The eth1 interface
uses a publicly accessible IP address. In addition to the physical eth0 interfaces, there is a virtual eth0
IP address that is used to manage the cluster.
The default gateway is connected to a firewall, which must be configured to allow traffic to the publicly
accessible IP address. Users with ShoreTel Mobility Clients running on their mobile devices access the
publicly accessible IP address to create tunnels so that they can use Secure Remote Voice and
Secure Enterprise Services. An example of this network configuration is shown in Figure 27.
There is also a virtual eth1 IP address, which is a publicly accessible IP address. For a redundancy
cluster, the virtual IP address is used rather than the physical IP address because the virtual IP
address remains constant if failover occurs and the standby takes the active role. For information
about redundancy clusters, see “Managing Redundancy Clusters” on page 227.
