    A & B

    The following list provides some common reasons to alter predefined applications:

    • You want to use a different port number for an application than that which is predefined, because not using well-known ports might help you increase security.

    • You want to increase or decrease the predefined timeout value to alter how long an application can be inactive before it times out.

    • You want an application to ignore the ALG, which effectively disables the ALG for that application, but still keep the ALG enabled for other applications. (If you actually disable the ALG, the ALG is disabled for all applications).

    To alter predefined applications, create a new application with the same name as the built-in application. Create the new application under the [edit applications] hierarchy. Remember that to view built-in application, issue the command show groups junos-defaults applications. The same options exist for altering a built-in application as for creating a custom application. You must configure only the options you want to alter. The following example alters only the inactive timeout for the junos-ftp application from 1800 seconds to 3600 seconds; the other options stay as predefined.
    [edit applications]
    user@srx# show
    application junos-ftp inactivity-timeout 3600;
