VLANs from the core router won't propogate across the trunk port on the HeX PoE router

I have a core Cisco router with voice and data VLANs. Voice VLAN 102 and data VLAN 103. On the Mikrotik router, I have a wan bridge setup with ether1 - 3. I’m using ether1 as a trunk port where I’m tagging 102 and 103. I have ether2 untagged for 102 and ether3 untagged for 103. The Bridge PVID is 102. If I assign the wan bridge as the DHCP client, it receives a proper lease from VLAN 102 but VLAN 103 doesnt show up and service dhcp on ether3. Any suggestions or guidance would be most appreciated! I’m must be doing something wrong. Thanks

Why do you want to use the hex as a router and simply not a switch??
