Out-of-path mode also allows two WebMuxes to fully backup each other. Two
WebMuxes connected to each other through a cross-over Ethernet cable.
Two simple changes must be made to each server in the farm. 1) To have a new
loop back adapter installed and have its address set to the farm address. Do not
set the gateway on the loop back adapter. Please refer to Appendix 1 and
Appendix 2 for how to configure a loopback adapter, as well as how to remove
the route from the servers. Please note for Out-of-Path to work properly, the
loopback adapter must route the return traffic through the real network
interface. Please refer to Appendix 1 and 2 for more details on how to
configure the loopback adapter on servers. In case the server running
Windows 2003, the route created during adding loopback adapter cannot
be deleted, please make sure loopback adapter has much higher metric. 2)
If your service is bind to any specific IP address, add the loopback adapter’s IP
address to that service.
The firewall configuration must be changed to point to the new farm address on
the WebMux. Since WebMux always uses one IP address in the server LAN, the
farm address must be a different IP address in the server LAN in Out-of-Path
mode.
