Cannot access my LAN over remote WireGuard VPN

RouterOS Beginner Basics
1

Hello,
i have probably easy problem, but i can’t solve it myself. Im looked on the forum similar problem but i can’t find any working solution for me.

I have MT router (10.10.10.1, network 10.10.10.0/24) and my own NAS server (10.10.10.2). All working fine, if i don’t using WireGuard connection to other location.

I sometimes need to use WireGuard VPN connection to connect to the other LAN in other localization for work. After i set up a WireGuard connection i can access remote LAN (Router - also MT, NAS server and other client’s). But after im connected to the WireGuard VPN i cannot access my local NAS Server.

What firewall rule (or something else) i need to setup on remote router to allow VPN users to reach their own LAN? I have admin rights for their MT router.

My Guess is the allowed IPs setting in your PC’s wireguard client.

A setting that should work would be 172.16.0.0/24, 10.11.11.0/24

Unfortunately it is not solving the case.
My allowed IP is set as 0.0.0.0/0, but for test i set it to my local network, and i still cannot access my local nas :frowning:

Ok i found a solution.
In AllowedIPs must be set to 0.0.0.0/1, 128.0.0.0/1. 0.0.0.0/0 means all the traffic goes throught the VPN Gateway and it avoid LAN.
