Hi,
I tried some test setups with VLAN tagging.
I used RED 50 only with connected WAN1.
After playing around with VLAN settings no connections is possible (RED tunnel).
I recabled Internet uplinik to WAN2 and RED tunnel came up.
Can you please check the config located at cloud service.
I tried to setup LAN port 4 to tagged 14,1000. May be WAN1 got some misconfiguration from my VLAN configuration.
