Ability to specify WAN for firewall rule

I’m using a Peplink Medifast 500 router, which I just purchased recently. I was hoping that this router had the ability to apply firewall rules to a specific WAN interface. For instance…

WAN1: Verizon Fios, All traffic allowed
WAN2: 4G service, Block a specified subnet from access, otherwise all other traffic allowed
WAN3: Satellite service, Block all traffic, allow only specific IPs

This question has been asked before but there isn’t a suitable answer in the forums. An outbound policy is not sufficient to accomplish what I’m asking.

You can apply inbound firewall rules to specific WAN interfaces - if you block inbound traffic destined to an internal subnet even if they try and send traffic out of that WAN they can’t do anything as traffic coming back will be blocked. Outbound policies can be used to direct outbound traffic from specific subnets to the right WAN links with good levels of granularity.

A combination of outbound policies and inbound firewall rules will be able to do what you want I would think.
