WebRTC IP Leak

[thankuverymuch]

ublock WebRTC option does not work
There seems to be a conflict with opera own WebRTC option
Real IP leak when ublock webrtc option is set in opera vpn

I confirmed that it does not work in firefox and chrome
webrtc test was done at doileak.com

Real IP leak when ublock webrtc option is set in opera vpn

only local IP is hidden, not your public IP, anyways fill the template and do not bypass it.

[thankuverymuch]

The answer sounds like garbage
Have you tested it?
It's a useless option in the latest Firefox, Chrome, and Opera.
It messes up the settings of Opera

It messes up the settings of Opera

The Opera's WebRTC option is undoing uBO's settings and uBO will only hide your local/LAN IP address, your public IP address will always be seen- https://github.com/gorhill/uBlock/wiki/Prevent-WebRTC-from-leaking-local-IP-address

[thankuverymuch]

You are telling a useless story now.
When ublock webrtc setting is checked and tested, my real IP is displayed.
To make the setting of the opera jammed.
Turning off ublock option hides IP due to opera's webrtc settings

Please provide repro steps as asked in the template, I don't know anything about "opera vpn". Respect the template before lecturing us on how we deal with issues.

[thankuverymuch]

I'm just talking about a bug that ublock's webrtc option forces off opera's webrtc option.

[gwarser]

By default Opera 71.0.3770.148 has WebRTC option set to "Use any suitable network interface (recommended)"

Installing uBO changes nothing.

Switching uBO option "Prevent WebRTC from leaking local IP addresses" makes it "Use default public network interfaces only" and disables this widget in settings:

Disabling uBO option "Prevent WebRTC from leaking local IP addresses" makes it work again and restores previous selection.

For everything above doileak.com reports that my public IP is visible (I don't have any private IP)
"Your browser supports WebRTC! Your real IP address is visible to every website you visit."

Choosing Opera option "Disable non-proxied UDP" makes Doileak report: "WebRTC IP Leak: We could not detect an IP via WebRTC."

All works as expected. What is the issue?

[uBlock-user]

What is the issue?

I believe the user prefers Opera's behaviour instead of uBO's, so in that case, the solution is to disable uBO's setting and let Opera control the behaviour.

[thankuverymuch]

All works as expected. What is the issue?

If ubo's webrtc ip address leak prevention option is checked, my real ip is leaked even if vpn is used. If the option is turned off, the IP is hidden due to Opera's webrtc option. Why does this option exist? If you think this isn't the problem, it looks like there's a problem with your head.

[uBlock-user]

Why does this option exist?

To prevent the leakage of local/LAN IP address, if you like Opera's behaviour of hiding both, just use that.

[gorhill]

I had no idea Opera had such a setting, hence why I asked for repro steps.

[gorhill]

I aapreciate there is an issue but I am unhappy with @thankuverymuch's resistance to properly fill rhe template and provide detailed repro steps. We will take it from here.

[gorhill]

All the typos is because I am on phone and efiting does not work well on Fenix.

With Opera VPN enabled, when using "Use default public network interfaces only" preference, IP is leaking always. Does not matter if it's set manually or by uBO.

[gwarser]

Wow, this was unexpected, looks like my LTE modem is working as local network. With "Use default public and private network interfaces only" Doileak reports: "Your local IP: 192.168.8.101
. Your public IP:XXXX"

No matter if with VPN or not.

uBO disabled.

---

Turning VPN "on" automatically switches WebRTC settings to "Disable non-proxied UDP"! And it can be changed, settings widget is not disabled.

With uBO "Prevent WebRTC... " option enabled, this does not work.

FINALLY! One simple STR would change a lot!

Now occuring with Vivaldi - https://www.reddit.com/r/uBlockOrigin/comments/jf9lj1/activating_prevent_webrtc_from_leaking_local_ip/

Disable non-proxied UDP

That setting disables WebRTC completely, that's why public/local IP is not shown.

essentially duplicate of gorhill/uBlock#2853 ?
