User manual

The WebMux™ Model 480S, 580SG, and 680PG User Guide – Version 7.0.x

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. In other words, the loopback adapter cannot have the gateway

specified. Please refer to Appendix 1 and 2 for more details on how to

configure the loopback adapter on servers. In case the server is running

Windows 2003, the route created during adding loopback adapter cannot

be deleted; please make sure the 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 the 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.

NOTE: Under normal Out-of-Path operations, you will only need to set the external gateway IP

address for the WebMux™ . However, if you are going to have the WebMux™ do SSL

termination or Layer 7 load balancing, you must set a server LAN gateway IP in the WebMux™

and have the servers’ default gateway point to that IP address.
