Hi
If you want devices on the LAN to be able to access the Guest network, but not vice versa, simply enable forwarding from the LAN to the Guest network in the default configuration.
We verified this locally using BE9300 with firmware 4.8.2 beta and drop-in gateway enabled, and it works as expected.
Please note that if you need to access devices on the BE9300 Guest network from the AX1800 LAN, it also needs to do:
- Configure a static route from the AX1800 to the BE9300 Guest network.
- Configure the BE9300 to allow WAN-to-Guest traffic forwarding.
