I have connected my Asus AXE-16000 router as an access point to Firewalla Gold Pro (router). Both are connected using the 10Gbps LAN port 1 on Firewalla to one of the 10Gbps LAN port on Asus router. Then, I created a new VLAN network on Firewalla using LAN port 2 with VLAN ID 50 and IP 192.168.50.1. Then, I connected it to LAN port 1 on the Asus router. In my Asus router, I have already created a new profile to add VLAN for the guest WiFi and assigned it VLAN ID 50. Also, I selected LAN port 1 and assigned it the guest WiFi (SDN VLAN Profile). I'm able to connect using the guest network if I select mode as 'Trunk' on Asus's LAN port 1. Things stop working when I select 'Access' as the mode. I have a dedicated ethernet cable going from Firewalla to Asus for the guest WiFi. So, it should work if I setup LAN port 1 in Asus as access port. However, it only works when I set the port as trunk. Any idea what is going wrong here?

  If you use VLAN, you need the trunk mode so Asus won't drop VLAN tage while processing packets to Gold Pro.
