[Solved]Wi-fi no internet

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello everyone.Tell me please. There is no Internet connection when connecting to Wi-fi Amnesia5g, while the connection to my vps works and when using a vpn connection through the client installed on the phone, everything works. Here is my configuration, most likely I messed up something in the firewall settings?:

Firewall is fine.

You need to do Policy Based Routing and you have 3 options:

  1. mwan3 package
  2. pbr package
  3. a set of rules/routes for each internet connection.

You have 2 gateways, the lan and the amnezia. If you don't do policy routing all packets are forwarded to the lan gateway. With policy routing packets from vpn interface can use the gateway of amnezia.

Please tell me how to do this through policies or pbr based on the existing configuration?

Given that the setup is based on guest wifi on a dumbAP, you shouldn't need pbr.

At first glance everything looks correct, except you missed the the option route_allowed_ips '1' in the peer section (which is really important).

Also, port 1 cannot be an untagged member of more than 1 vlan, so remove it from vlan1 (first make sure that port 1 is not used as an uplink to the main router).
