Tailscale on the GL-A1300

Routers
1

Hi Everyone,
I wonder if anyone has run into the same or similar issue with tailscale as I have found recently.

I have been experimenting with Tailscale with my GL-A1300 router as I would like to use this while travelling. I currently have a "tailnet" configured that has devices configured to "expose" my internal LAN to other machines on the tailnet. I have noticed with tailnet enabled on my GL-A1300, if I try to "ping" from my computer connected to the WIFI of the GL-A1300 I am unable to connect to or get a response from a device on the internal lan. However, if I use SSH and connect to the GL-A1300 and ping the same IP 172.26.5.50 I am able to get a ping response.

Is there something in the configuration that I have completely missed or is this a known issue where something has to be manually configured?

I have checked via the CLI that the routes show and the same is present under the LuCI interface so from my point of view this should be working. I have also checked the configuration of the firewalls on other devices and that all looks good.

Is this something that anyone else has seen before or had any experience with?

Regards,
Tom

  1. Whether network isolation is enabled on the router.
  2. It is recommended to check the routing table again to see if there are any priority or routing conflict issues.

Hi Alen,
I have been working on this again today. I have checked the routing table (screen shot below) and it shows correct from what I can tell via the LuCI interface.

Still if I try and ping from a client device a device on the 172.26.5.0 subnet I do not get a response. However if I do the same from the Routers SSH Command line i get a response.

Any other pointers are welcome, I can't find anything int he firewall to allow traffic to pass to the tailscale network so is this the problem?

Regards
