In my case with Android 12 and Tailscale version 1.36.1 Exit node does not work at all, although on Linux machines work without any issues.

DentonGentry commented 1 year ago

The exit node not working is a different issue, this is about Allow LAN Access not working. If you want to file a new issue and include a bugreport from the Android app while it is trying to use the exit node, we can look into it.

I have been using Tailscale with the same setup since September 2021, but this feature has never worked for me on Android.

OS

Android

OS version

Android 13

Tailscale version

1.38.1

Steps to reproduce

I have an AWS EC2 Ubuntu server that I have advertised as an exit node (let's call it aws-sg).
I have approved aws-sg as an exit node on the Tailscale admin page.
My Windows, Mac, and Android machines are connected to the same network (192.168.70.0/24) through wifi.
On all three devices, I run Tailscale and use the aws-sg exit node with "Allow Local Network Access."
My Windows, Mac, and Android machines are now connected to the aws-sg exit node (I can confirm this by using check IP websites, and it shows the AWS EC2 IP).
My Windows and Mac can continue to access devices in the 192.168.70.0/24 network.
However, my Android device is unable to access devices in the 192.168.70.0/24 network.
It seems like the "Allow LAN access" feature on Tailscale's Android app doesn't work at all.

Device	Exit node used (Allow LAN Access)	Able to access 192.168.70.99
Mac	aws-sg	✅
Windows	aws-sg	✅
Android	aws-sg	❌

It still doesn't work on 1.40.0 from F-Droid on Android 13. Never worked for me also.

Zocker1999NET commented 10 months ago

Can sadly still confirm as well, Android 13, LineageOS 20, Tailscale 1.44.1, from F-Droid.

Steps to confirm using an exit node is the problem:

without Tailscale, try to connect to a local device (e.g. router via browser), it works
turn on Tailscale with exit node & allow LAN access
check access to router again, does not work
turn off exit node, letting Tailscale itself enabled
check access to router again, now it works again

It seems work well at v1.48

Craeckie commented 6 months ago

Still doesn't work for me on the recent commit b88929e, which F-Droid version "1.55.47" appears to be built upon (see F-Droid)

It seems work well at v1.48

What device&OS are you using? Did you change something since your previous post? This information might help to narrow down the cause of this issue.

Orhideous commented 6 months ago

Same issue. Android 13, Tailscale 1.53.115-t6cce5fe00-gab4a672a4eb from F-Droid. It never worked for almost a year.

bailey-ts commented 6 months ago

While replicating this issue for a customer (go/hs/25484) I also observe this behavior on my Pixel 6a, Android 13 (LineageOS 20), client version 1.54.0-tc82fd1256-g8e8e1d0f76a

Same issue here with Tailscale 1.5.6 on both my Pixel 8 Pro (Android 14) and on my Chromecast (Android 12). 'allow lan access' has no effect. This has the side effect of breaking casting from Android to the Chromecast/Android TV while the exit node is enabled.

I'm also still encountering this issue using Mullvad exit nodes on Tailscale 1.57.72 for Android. This issue sounds similar to #10526, so Android isn't the only platform affected.

tnchan007 commented 4 months ago

An android user go/hs/28841 can't access any local LAN IPs 10.x while connected to Tailscale with Mullvad exit node enabled and the Allow LAN access feature enabled. When Mullvad exit node is disabled local IPs are accessible without issue.

Same problem here with latest Tailscale on my Chromecast with Google TV (Android 12). "Allow lan access" does not work. Therefore no connection to my local NAS possible if tailscale is active.

mathmaniac43 commented 3 months ago

Same issue. Running Tailscale 1.58.2 (from F-Droid) on Android 11

Orhideous commented 3 months ago

It looks like that this problem is more common. In a next few days I'll try to find a clue what happened.

DTBUday commented 1 month ago

Any updates on this? This issue seems to still be a problem for version 1.60.1

DTBUday commented 4 weeks ago

Seems to be fixed with version 1.66

tradergene commented 4 weeks ago

Fixed for me as well on Android. Finally! And thank you to the Tailscale team.

Sadly, even on 1.66, the toggle now simple breaks the VPN (the key disappears from status bar, Tailnet no longer accessible) for me, on all of my Android devices. :cry:

steigerm commented 3 weeks ago

Same here. Even with 1.66 it does not work on my Chromecast with Google TV (Android 12).

Connect VPN "Allow lan access" OFF Communication using Exit Node works Local LAN access not.

"Allow lan access" ON Communication using Exit Node does not work Local LAN access works.

5310 commented 3 weeks ago

@steigerm are you on Android 11 by any chance?

steigerm commented 3 weeks ago

Nope. From my original post "Same problem here with latest Tailscale on my Chromecast with Google TV (Android 12)."

5310 commented 3 weeks ago

(Well, that was embarrassing :blush:...)

But I'm now convinced Allow LAN is working on Android 13 and 14, but not on Android 12 and 11 (at least). Tested a total of twelve phones, and this holds for all of them running 1.66.3

Only one of the reports in this thread was from A14, but that was long before the fix actually landed (as with the rest of the A12 and lower, to be fair). Hope it can get fixed someday, as my phone is stuck on A11 for a year at least!
