Hello.
I have a device on the LAN with a reserved IP eg 10.0.0.10/255.255.255.0
Using the very limited web interface I am trying to setup an IPv4 firewall DENY rule to deny that local IP address any access to any IPs on the internet whilst still allowing access within the LAN ... but have bounced. No matter what IP range I enter for WAN, eg 1.1.1.1-255.255.255.255 it flags it as invalid.
Could some kind soul provide instructions ?
