SteelHead™ Deployment Guide : WAN Visibility Modes : Configuring WAN Visibility Modes
  
Configuring WAN Visibility Modes
This section describes how to configure WAN visibility modes using an example deployment and the RiOS CLI.
You configure WAN visibility modes by creating an in-path rule on the client-side SteelHead (where the connection is initiated). By default, the rule is placed before the default in-path rule, and after the secure, interactive, and RBT-proto rules.
For transparent addressing to function correctly, both of the SteelHeads must have RiOS v5.0.x or later installed. If one SteelHead does not support transparent addressing (that is, it has RiOS v4.1 or earlier installed), the SteelHead attempting to optimize a connection in one of the transparent addressing modes automatically reverts to correct addressing mode, and optimization continues.
By default, SteelHeads use correct addressing (for all RiOS versions).
Figure 3‑17 shows the IP addresses and ports used in the example deployments.

The following table summarizes the port transparency CLI commands.
Action
CLI Command
Enable port transparency for a specific server
in-path rule auto-discover wan-visibility port dstaddr 192.168.50.1/32 dstport 80
Enable full address transparency for a specific group of servers, and port transparency for servers not in the group
in-path rule auto-discover wan-visibility full dstaddr 192.168.0.0/24
in-path rule auto-discover wan-visibility port
Important: In this example, the first in-path rule must precede the second in-path rule in the rule list. To specify the placement of a rule in the list, use the rulenum CLI command option. For details, see the Riverbed Command-Line Interface Reference Manual.
Disable port transparency
Delete the in-path rule that enables it. For information about deleting in-path rules, see the Riverbed Command-Line Interface Reference Manual.
The following table summarizes the full address transparency CLI commands.
Action
CLI Command
To enable full address transparency globally
in-path rule auto-discover wan-visibility full
To enable full address transparency for servers in a specific IP address range
in-path rule auto-discover wan-visibility full dstaddr 192.168.0.0/16
To enable full address transparency for a specific server
in-path rule auto-discover wan-visibility full dstaddr 192.168.50.1/32
To enable full address transparency for a specific group of servers, and port transparency for servers not in the group
in-path rule auto-discover wan-visibility full dstaddr 192.168.0.0/24
in-path rule auto-discover wan-visibility port
Important: In this example, the first in-path rule must precede the second in-path rule in the rule list. To specify the placement of a rule in the list, use the rulenum CLI command option. For details, see the Riverbed Command-Line Interface Reference Manual.
To disable full address transparency
Delete the in-path rule that enables it. For information about deleting in-path rules, see the Riverbed Command-Line Interface Reference Manual.
