Configuring the WSM using Device Manager

Configuring IP proxies with Application Redirection

When used with Application Redirection, transparent proxies for NAT redirect client requests to servers located on any subnet, anywhere. They are transparent to the user and substitute all source and destination addresses, including remapping destination ports.

Note: Application redirection is automatically enabled when a Redirect filter is applied to a port.

This configuration assumes that Application Redirection is configured for your network.

To configure a proxy IP address for NAT:

1. Add proxy IP addresses to the SLB ports as follows. See Configuring a proxy IP address for a port.
• If VMA is not enabled, add proxy IP addresses to the redirection ports.

Each port using a redirection filter requires a unique proxy IP address.

• If VMA is enabled, add proxy IP addresses for all WSM ports (except port 9). For information about VMA, see Improving WSM performance with VMA.

Set the following SLB port parameters.

­	Port = <port number>

­	Proxy IP Address = <proxy IP address>

­	Proxy IP State = Enabled

2. Configure the application redirection filter to use the real server TCP or UDP port to which redirected traffic will be sent. See Creating a new filter. Set the following parameter.

­	Redirection Port = <the proxy redirection port number>

3. Enable proxies on the real servers. See Configuring each real server. Set the following parameter.

­	Client Proxy = Enabled

4. Verify that traffic has been redirected. See Filter statistics.
