WLAN tunnel mode and VLAN ID
We have a guest WLAN "guest1" (not in tunnel mode) with VLAN ID 4 in our headquater and want to use the hotspot gateway in this VLAN also for our branch offices in future.
My idea is to create a WLAN "guest2" on the Access Points in branch office and configure that with tunnel mode. Do i have to use the same VLAN ID 4 for branch office WLAN to direct the traffic to our hotspot gateway in headquater even if this VLAN does not exist in branch office?
We have redundant ZD's in our headquater and VPN connection to our branch offices.
