Here’s my situation. I have a ubiquiti nanostation with 2 wireless SSID trunking to a mikrotik 450G. I have one port on the mikrotik trunked with both vlans. Everything wirelessly works perfectly. I’d like to also have one of the VLANs span the bridge so I can have one wireless network and 3 wired ports on the same vlan. I have tried adding a switch rule to put the ports in VLAN 55 which is that vlan, but it is not working. I would expect to be able to plug in a wired device and receive a dhcp address from the pool i have configured on VLAN 55, but it’s not working. Any thoughts?
The MikroTik is a router not a switch, therefore it cannot and does not handle VLANs like another layer2 device will. When you add in a VLAN it makes a virtual interface for that VLAN. As far as I’m aware the only way to do what you want to do is bridge the VLAN you want with the desired Ethernet ports. You also cannot bridge the VLANs with the Ethernet port they are on.
