Recipe Environment¶
In this recipe, TNSR uses the WAN-side VR address (203.0.113.228) for
outbound NAT from the internal private subnet 10.28.0.0/24. Clients will use
the LAN-side VR address (10.28.0.1) as their gateway.
Interface tracking is included in the example to protect against a single failure of either WAN or LAN.
The configuration commands in this recipe apply the settings from these sections to each node. Some additional settings in the commands are omitted, but the recipe commands include them with default values for emphasis.
