Example: You have an FTP server connected to P6 (in the DMZ zone). You want to limit the amount of FTP traffic that goes out from the FTP server through your WAN connection.

1Create an address object for the FTP server (Object > Address).

2Click Configuration > Network > Routing > Policy Route to go to the policy route configuration screen. Add a policy route.

3Name the policy route.

4Select the interface that the traffic comes in through (P3 in this example).

5Select the FTP server’s address as the source address.

6You don’t need to specify the destination address or the schedule.

7For the service, select FTP.

8For the Next Hop fields, select Interface as the Type if you have a single WAN connection or Trunk if you have multiple WAN connections.

9Select the interface that you are using for your WAN connection. If you have multiple WAN connections, select the trunk.

10Specify the amount of bandwidth FTP traffic can use. You may also want to set a low priority for FTP traffic.

Note: The ZyWALL checks the policy routes in the order that they are listed. So make sure that your custom policy route comes before any other routes that would also match the FTP traffic.
