Network Configurations
How you configure remote access depends on your network configuration. The following lists the most
common network configurations for which you can implement remote access:
 “Network Includes NAT with Firewall” on page 43
 “Network Excludes NAT” on page 44
 “Network Uses Mobility Router Redundancy Cluster and NAT with Firewall” on page 45
 “Network Uses Mobility Router Redundancy Cluster Without NAT” on page 46
Network Includes NAT with Firewall
In this network configuration, the Mobility Router uses the eth0 interface for communication to a default
gateway and the internal network. The eth1 interface uses an internal IP address. The default gateway
is connected to a firewall using NAT with a publicly accessible IP address. Users with ShoreTel Mobility
Clients running on their mobile devices access this 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 24.
