I have a router / modem called ZTE ZXHN H298A V1.0 TTN.19T4_210317.
I'm sharing my network with neighbours but I want to capsule my network and/or the guests network to protect my local network. So I tried to create a VLAN for the guest's WiFi but I get an error message "Current operation is invalid, please check configuration parameters.".
See my try in the screenshot: VLAN Config
How can I isolate my network (all LANs and SSID1 and SSID5) from the guest's network (SSID2 and SSID6) correctly?
Thanks
