Hi there,

I am having trouble with getting the trunk to work between my ER707-M2 and my already existing Fs S3400-24TFP POE switch.

I have wirless A/Ps, the omada controller and other devices plugged into the Fs switch and a trunk port  (port23) to the ER707-M2 router (port6) for the firewall/internet.

I have 4 vlans that I need, vlan 85 (main), vlan 50 (guest) vlan72(IOT) and vlan1 is the native vlan. I have the trunk port set to vlan1 and each vlan has a ip set in the switch that coincides with the corresponding vlan subnet in the omada controller firewall/router setup.

I can access the internet / network fine if any of the ports are set to vlan1 in the Fs switch but the moment set them to any of the other vlans I need i don't get a connection unless I change the native vlans I'd then all I get is that vlans subnet range.

Even with the wifi ports set to vlan1 trunked and untag the other vlans and the ssids assigned the the corresponding vlan in omada I get no ip assigned to any wifi devices unless I connect to the main ssid that is assigned to vlan1.

Vlan1 = x.x.0.1

Vlan50= x.x.50.1

vlan85=x.x.85.1

Vlan72=x.x.72.1

I have even had AP ports set to the wrong vlan and I still get the AP adopted. Ap sitting on a vlan85 port but only addressing out vlan1 address's the wifi works fine but still on wrong subnet.

I have no issues getting on the default Vlan1 but that's it.

I have no idea what I am missing.

I have set up trunking with fs switches to fs switches with a ton of vlans in the past and haven't had this much trouble.

Can someone please give pointers.

Thanks
