| Configuring the WSM using Device Manager |
|
When requesting services from the virtual server, a client sends its own IP address for use as a return address. If you configure a proxy IP address for the client port, the WSM replaces the client's source IP address with the WSM's own IP address as a proxy before sending the request to the real server. This makes it look to the server like the WSM originated the request.
Note:
When a proxy IP address is configured, requests appear to come from the WSM rather than the client. For this reason, the network administrator performing debugging and collecting statistics must be aware that a proxy IP address is configured.
The real server uses the WSM's proxy IP address as the destination address for any response. SLB traffic is forced to return through the proper switch, regardless of alternate paths. Once the switch receives the proxied data, it puts the original client IP address into the destination address and sends the packet to the client. This process is transparent to the client.
Note:
If VMA is enabled, all ports must be configured with a unique proxy address when any WSM port is configured with a proxy IP address. If VMA is disabled, only the client port needs a proxy IP address. Port 9 does not require a proxy address when VMA is enabled.
