How to set up vlan in dd-wrt?

Question

WiFi

There is a router stitched dd-wrt. A cable from our local network with the Internet is connected to the WAN port. The IP of the van port is 192.168.1.3, the IP of the local network is 192.168.2.1, the task is this: you need to restrict WiFi access from the 192.168.2.1 network to the 192.168.1.3 network, but leave access to the Internet. Simply put, you need to create a guest wifi that does not have access to the first network.

Answer 1

Alas, there is no such thing, you need to do it manually somehow :(

Answer 2

So dd-wrt has a function to create a Guest WIFI which blocks access to the local network.
