Can i separate the OpenWrt's Router-Network from the Network over it?

Is it possible to use the Firewall in OpenWrt so that devices from a network over the OpenWrt-Router cant access my "private network"? If it's possible please let me know :slight_smile: Sorry for my bad English.

@moritztelefon, welcome to the community!

If you create a second LANs and place it in different firewall zones - forwarding between them is disabled by default
