When using dual network interfaces on an Expressway server, the default gateway must be set to the firewall address. The drawback of this is internal traffic gets routed toward the public interface rather than back to the internal interface, which can be a problem when clustering the Expressway servers. The solution is to add a static route for the internal networks to the Expressway server.
Login to the CLI using the admin account. When prompted to run the setup wizard, type ‘n’.
Enter the following command to create a static route, replacing the route address with your own internal subnet.
xCommand RouteAdd Address:192.168.0.0 PrefixLength:16 Gateway:192.168.125.254 Interface:LAN1
