UniFi OS 2.4.27

I upgraded my UDM Pro to UniFi OS 2.4.27 and then installed tailscale-udm and it is working properly for other endpoints as an exit node. I have several other USG3s with tailscale installed and functioning with advertised routes that I plan to set up in a site-to-site configuration however it seems I am not able to set up subnet routing of local subnets to the other USGs as lightly mentioned in the FAQs that were written prior to the release of 2.4.27 on a UDM Pro. Perhaps @tomvoss has tested 2.4.27? The current issue is that the UDM shows tailscale status as up and it sees its peers yet cannot ping the tailscale peer IPs.

I'm using unifios-tailscale. I found an issue during install that I think was caused by not having a proper .env file setup before running the install script. Once that was fixed the install succeeded.

The first 2.4.27 router I ran this on experienced recurring, seemingly random issues where Tailscale routes suddenly stopped working. Ultimately I reverted that router to older firmware and an older release of unifios-tailscale. I still don't know if the issue was directly related to unifios-tailscale or not.

I've since upgraded two other routers to 2.4.27 and installed unifios-tailscale and they are working perfectly. So I'll give it a YMMV rating. I'm monitoring the situation before I upgrade the rest of my routers.
