Expose Tailscale subnet to LAN

I'm running Tailscale on my router, using --accept-routes option, because one of my remote tailscale node advertise subnet.

With my laptop, I can ping any tailscale node without issue (with the OpenWrt Router being the "nexthop")

But if I try to ping a device I receive a From icmp_seq=9 Destination Net Unreachable (I have no idea on who is)

If I ssh into the OpenWrt and ping any devices, they will respond.

I followed the instruction of the wiki

Any ideas?

I'll take a guess that is a router in your ISP's network, which means that although your Tailscale install is accepting routes, the traffic from your laptop isn't being pushed through them.

Can you give the output of

ip route show

on the OpenWRT device, please?

root@OpenWrt:~# ip route show
default via dev br-lan dev br-lan scope link  src

It may be useful to know that this OpenWrt is not the main router, it acts like an access point and a switch.
