It seems that you have a misconception about VLANs. Your LAN interface is now configured to receive IP address, netmask and gateway data from device, which will be connected to the associated port.
LANPORT2 and LAN3 are within the same subnet, based on their netmask notations. Please check this link on port based VLAN configuration details for Teltonika devices.
Now, if your goal is to reach all the LAN devices, is there a purpose for additional VLANs? Or is your goal to reach devices in LAN from different subnets? In this case, you would simply need to add VLAN interfaces to a firewall zone associated with LAN, which is likely done by default.
