The back-end, load-balanced, servers "see" the real client IP address when running in 2-Armed NAT mode. That means that the servers must be configured to route back through the WebMux instead of any other default route. The WebMux has a "Server LAN Gateway" value that should be set to an IP address on the subnet of the back-end servers. That is the IP address that those servers should use as their default gateway. In a high-availability configuration, with two paired WebMux units, that "Server LAN Gateway" IP address floats between the two units depending on which is ACTIVE
Features:
- Traffic goes back through the WebMux to the original client
- 2-Armed NAT means the client traffic comes into the WebMux, is load-balanced across the back-end servers on a separate interface
- WebMux must be the default gateway for the servers.
- At least two connections are used, for the two sides of the NAT. In a four-port unit there can be aggregation between two links on each "arm
