Dual-WAN Bridge

Hi,

I have HEXs, anI I wish to use him as a Dual-WAN in bridge mode. My network architecture is the following:
ISP 1: SFP - PPPoE
ISP 2: Lan1 - PPPoE
My Velop router connects my entire network and I’m planning to connect him to the HEXs Port 5 (for example), and I want him to get the public IP (instead of another NAT). How can I achieve this?

I want to create a failover policy or load balance on both ISPs.

Thank you
