Example 2. 1 x Wan Link, 1 X LTE for failover with a Concentrator
This configuration provides a resilient private connection between the remote site and the head-office net-
work. In the event of the primary (WAN) link failing all traffic is routed via the secondary (LTE) link.
All traffic from the remote site is routed over the private tunnel to the head office network. The firewall does
not masquerade any packets and 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.
