Problem configuring VLANs, PROXMOX, SOPHOS, MIKROTIK

[Komanoid]

Hi, I have a problem configuring VLANs

DEVICES:
proxmox_main 3xNIC (WAN, LAN, DMZ)
-VM SOPHOS bridges to all NICs (vmbr0, vmbr1, vmbr2(DMZ)

proxmox_dmz 1xNIC (DMZ)
-VM1_DMZ
-VM2_VL1721

MikroTik RB260

I have declared VLAN id 1721 on sophos in DMZ zone

I want VLAN_1721 and the DMZ network to exit from PROXMOX_MAIN enter the MIKROTIK with PORT #4 and then exit with PORT #3 and enter PROXMOX_DMZ where VM1 will be able to be in the DMZ network and VM2 in VLAN_1721



PROXMOX MAIN(with SOPHOS)

PROXMOX DMZ

MIKROTIK VLAN
