Beryl AX connected to Spitz v2 via Ethernet from the box. I need this because I don't have cable connection (only 4G) and Spitz v2 too weak to work as VPN or network filter alone.
I turned off radios on Spitz v2, so it only used as WAN for Beryl AX.
So...
How can I access Admin Panel of Spitz v2 in this config? I mean how can I access admin panel of Spitz v2 while being connected to Beryl AX?
According to this topology you attached, you can access Spitz's GL GUI by accessing http://192.168.200.1 in the address of the browser in the client of Beryl AX.
If it is unbale to access, please check the current Failover priority of Beryl AX and whether the WAN being used is Spitz.
