Explanation:
Instead of using predefined services, you can easily create custom services. You can assign each custom service the following attributes:
Name
Transport protocol
Source and destination port numbers for services using TCP or UDP Type and code values for services using ICMP
Timeout value
If you create a custom service in a virtual system (vsys) that has the same name as a previously defined custom
service in the root system, the service in the vsys takes the default timeout for the specified transport protocol (TCP, UDP, or ICMP). To define a custom timeout for a service in a vsys that is different from the default when a custom service with the same name in the root system has its own timeout, create the custom service in the vsys and root system in the following order:
* First, create the custom service with a custom timeout in the vsys.
* Then create another custom service with the same name but a different timeout in the root system.
