Exit node working on ios but not on android or linux

exit node :
Tailscale version : 1.22.2
on raspian : Linux raspberrypi 5.10.63-v7l+ #1496 SMP Wed Dec 1 15:58:56 GMT 2021 armv7l GNU/Linux

ios : latest version
android: latest version
linux : rocky linux with tailscale 1.22.2

so i have a working network
and i want to use the raspian as an exit node.

this works with the ios client, but both android and linux don’t work
tailscale comes up but nothing works anymore.
i can’t reach any other machine on the tailnet, even on ip i can’t access anything outside anymore
but only on linux & android

any clues anyone?

From the linux machine, after running sudo tailscale up --exit-node 100.x.y.z to connect to your exit node, please run tailscale bugreport and either post back the code here, or email it to support@tailscale.com
