I have connected AC1300 with the main AX3000 5G router as a client through WAN <>LAN.
AC1300 has Tailscale turned on and connected to my Tailscale accout. As soon I enable Tailscale on AC1300 to use one of the exit nodes, any client connected to AC1300 gets no Internet. That exit node is perfectly working so the issue isn’t with the node. There was some guide here on the form that I once followed but can’t find it so fix this.
Have you approved the LAN subnet routes of the router in the Tailscale Admin Console?
If not, LAN devices won’t be able to get Internet because the Exit Node has no return route.
Thank you for the help. I did it earlier searching on some posts here on the forum. Guide was on running commands through SSH and had all routes approved in Tailscale admib, two were showing up.
The current A1300 is not advertising its LAN routes within the Tailscale network.
The current X3000 is not advertising itself as an Exit Node.
Therefore, we:
Create a Tailscale interface in LuCI and added it to the firewall with Masquerading enabled, so it could work even when the A1300 is not advertising its LAN route. If you prefer not to advertise routes, you may also refer to this configuration:
