Interface Limiter?

[ELCouz]

Hi,

I have one cable modem owned and another shared.

The network looks like this:

LAN  <–->      [pfSense] WAN1                <–-> Dedicated ISP1 [15mbit/10mbit] (Full bandwidth no restriction)
                                      WAN2 (failover) <–-> Shared ISP2 [30mbit/10mbit] (Would like to limit the WAN2 to 15mbit/5mbit up)

I know it's possible by IP but I would like to do the full interface WAN2 regardless of source/destination ip or port.

Any clues?

Thank you very much! :)

Merry Christmas & Happy new year!
