Real IPv6 is leaking to connected clients. "Disable IPv6 tethering" option does nothing for my phone.

@githuborer Have you tried reapply rules?

Hello,
on version 2.1.1>
yes I tried to reapply rules many times . My vpn IPv4 is applied after I reconnect the client to hotspot for first time.
IPv6 is still leaking.

Interesting. Your phone seems to be using a non-standard approach for IPv6 tethering (bridging). Can you try to run adb shell su -c 'echo 1 >/proc/sys/net/ipv6/conf/bridge0/disable_ipv6' and see if that fixes it for you?

@githuborer If you need further help, feel free to tell me. 😄

Hi, Thank you.
I checked out now option disable_ipv6=1 and IPv6 at client disabled immediately.
So VPN tethering is working well for clients, but only with IPv4.
Here is log after that.

Great. Now if only there is a way to reliably tell when the device will do this. Before that, I'm afraid you have to do this manually. 😛

Device disabled ipv6 tethering immediately while connected to vpn. Didn't need to refresh rules or reconnect clients. You could add some additional custom command options to your app to run scripts or something like that. I could do the rest to automate it
ps: Its an custom MIUI Epic ROM 9.0

I just noticed that you said you were using a custom ROM. Does official MIUI ROM also have this issue?

I can't answer your question. Use this custom rom for a long time and don't have other devices with MIUI

So based on #71, this bug seems to be exclusive to MIUI as they have implemented their own IPv6 tethering (entirely different from AOSP). Unfortunately, MIUI seems to be no longer open source so I will not provide support for MIUI.
