Assigning Servers to Service 67

Assigning Server to

Services (Advanced)

In addition to performing Network Address Translation, the Server Load

Balancer is capable of translating the TCP or UDP port on which the

service is operating. The virtual service can be configured for a well

known port, while the servers respond to an alternate port. For example,

a Web service is set up on the standard TCP port 80 and translated to

8080. When a request is received from a client on port 80, the Server

Load Balancer changes the port to 8080 before forwarding the packet on

to one of the available servers. When the server reply is received by the

Server Load Balancer, it changes the port number back to 80, then

forwards the packet on to the client.

To change the port, complete the following steps:

1 Click Server Assignments.

2 Click on the cell next to Server A. A pop-up menu appears.

3 Click Assign server to service (Advanced).... The Assign Server to Service

window appears.

4 Enter 8080 in the Server port field.

5 Click OK.
