Yes currently its set to dumb switch but i can change/tag them according to my needs. Ive already created VLAN1 on edgerouters side for other devices (unifi AP, pc). So this part should not be more difficult in case of VLAN2. Except trunking. So what im asking here would connecting tagged ports (vlan2) on edgerouter and tagged ports on the switch with second cable work? Or should i still try to push both tagged and untagged traffic to switch through one cable
