How to bypass wireguard client for local network on openwrt

Assuming your local network is 192.168.0.0/24, you should do this:

nano /etc/config/network

and add the following to your wireguard peer config section:

 list allowed_ips '0.0.0.0/1' list allowed_ips '128.0.0.0/2' list allowed_ips '192.0.0.0/9' list allowed_ips '192.128.0.0/11' list allowed_ips '192.160.0.0/13' list allowed_ips '192.168.1.0/24' list allowed_ips '192.168.2.0/23' list allowed_ips '192.168.4.0/22' list allowed_ips '192.168.8.0/21' list allowed_ips '192.168.16.0/20' list allowed_ips '192.168.32.0/19' list allowed_ips '192.168.64.0/18' list allowed_ips '192.168.128.0/17' list allowed_ips '192.169.0.0/16' list allowed_ips '192.170.0.0/15' list allowed_ips '192.172.0.0/14' list allowed_ips '192.176.0.0/12' list allowed_ips '192.192.0.0/10' list allowed_ips '193.0.0.0/8' list allowed_ips '194.0.0.0/7' list allowed_ips '196.0.0.0/6' list allowed_ips '200.0.0.0/5' list allowed_ips '208.0.0.0/4' list allowed_ips '224.0.0.0/3' option route_allowed_ips '1
