WAN connection.

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

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

Select the interface that you are using for your WAN connection (
ge2
and

are
the default WAN interfaces). If you have multiple WAN connections, select the
trunk.

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

sure that your custom policy route comes before any other routes that would
also match the FTP traffic.
