Redirecting Services - Symantec 360R - Security Gateway SGS Administration Manual

Redirecting services

port number. For protocols that use a single port number, the listen on port
starting and ending port number is the same.
You can also configure services to be redirected from the ports they would
normally enter (Listen on Port) to another port (Redirect to Port). Service
redirection only applies to inbound rules. Outbound rules ignore this setting.
For example, to redirect inbound Web traffic entering on port 80 and using TCP
protocol, to an internal Web server listening for TCP on port 8080, you would
create a new service application called WEB_8080. Select TCP as the protocol,
and type 80 for both the start and end Listen to Ports. For both the start and end
Redirect To Ports, type 8080. Then create and enable an inbound rule for the
Web application server that uses WEB_8080 as a service.
Note: Redirection port range sizes must be the same as the Listen on port
ranges. For example, if the Listen on port range is 21 to 25, the redirection port
range must also be four ports.
To redirect inbound traffic to the original destination port, leave the redirect
fields blank.
To configure a service
Create a service before you add it to an inbound rule. Once you create a service,
you can update or delete it.
See "Services tab field descriptions"
