Assigning Server To Services (Advanced) - 3Com SERVER LOAD BALANCER 3C16120 User Manual

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.
