Hello OpenWrt,
I successfully installed OpenWrt 23.05.4 on my Glnet GL-MT3000 router. The router is plugged into the ISP router (using it as a main router is not an option).
I have set up tailscale, and I can use the tailscale node as a exit router.
What I can't do, and have been trying to get working for the past two weeks, is access devices on the OpenWrt LAN (192.168.1.0/24) and WAN (10.0.0.0/24).
Here is the network diagram, OpenWrt Interfaces & Zones and Tailscale settings:
Tailscale was started using this command:
tailscale up --accept-routes --advertise-exit-node --advertise-routes=10.0.0.0/24,192.168.1.0/24 --netfilter-mode=off
So in summary:
I can access the internet via. tailscale (so the exit node functionality is working). But I cannot access the 192.168.1.0/24 or 10.0.0.1/24 subnets.
Can anybody see where I am going wrong?
Edited: Tried to make diagram easier to read, as a new user I can only have one image in a post.
