| Configuring the WSM using Device Manager |
When SLB is used without proxy IP addresses and without DAM, the WSM must process server-to-client responses.
If clients bypass WSM processing and access the real server IP address and port directly, the server-to-client response could be mishandled by SLB processing as it returns through the WSM. The real server IP address could be remapped back to the virtual server IP address on the WSM.
First, the real server must perform two port processing--one real server port handling the direct traffic, and the other handling SLB traffic. Then, the virtual server port on the WSM must be mapped to the real server port.
In the following figure, clients can access SLB services through well-known TCP port 80 at the virtual server's IP address. The WSM, behaving like a virtual server, is mapped to TCP port 8000 on the real server. For direct access that bypasses the virtual server and SLB, clients can specify well-known TCP port 80 as the real server's IP address.
Note:
Port mapping is supported with DAM when filtering is enabled, a proxy IP address is configured, or URL parsing is enabled on any WSM port.
