Example 1. 1 x WAN Link, 1 X LTE for failover without a Concentrator
This configuration provides a resilient Internet connection. In the event of the primary (WAN) link failing all
traffic is routed via the secondary (LTE) link.
All traffic from the private subnet to the public internet is masqueraded or NATted. No services or ports are
open on the external or public side of the firewall.
The integrate WiFi access point and the first 5 GbE ports are bridged into a single logical interface.
The diagram below shows the logical network diagram.
