Balance 580 in front of Asus TUF5400

Hi! I have a home setup with 2 WAN (Fiber 100Mbps + Starlink in ETH mode) connected to Balance 580 and, behind it, an Asus router to serve all LAN and mesh Wi-Fi connections throughout the house.

Does anyone know how to correctly set up Peplink and Asus to be able to use Peplink balancing rules for each home-connected user or device?

I guess I need to disable NAT on Asus, open all LAN IPs to Balancer, and do some Peplink magic =)

Balance IP and DHCP set to 192.168.10.1
Asus LAN IP is 192.168.50.1 (WAN IP 192.168.10.2)

I tried just disabling NAT on Asus, but it didn’t work. everything stopped
LAN and WAN connections from and between LAN devices
