I have the following setup.
The issue is multiple VLANs on one port in this case P2 coming from unRAID server.
pfsenese --> port 1 Tagged
VLAN5 on unRAID --> port 2 Tagged
VLAN6 on unRAID --> port 2 Tagged
The UNRAID server itself who hosts the 2 VLANS (5,6) has also the management interface which is also on the port 2 since there is only 1 network cable going from the unRAID server to the switch again (Port2).
So pfsense can see the unRAID server management page and the VLAN 5 but cannot see the VLAN 6, any idea how to fix this one ?
