Packet loss over bond

Hi, new fresh install on a physical box with 4 ports, 2 GbE and 2 10GbE:

eth0: wan1
eth1: wan2
eth2+eth3: bond 802.3ad LACP.

I’m experiencing packet losso between vlans.

i have also tried assigning ip at the lag and the switches in vlan 1.

10.10.0.254 → nethsecurity lag

10.10.0.253 → switch

no packet loss on the wan from outside, or from vpn to all lan interfaces on firewall side.

What can it be? is it supported to have vlan over a bond?

Thanks
