Hi 

 

The add on WebRTC Block for chrome is not longer working. 

Does anybody know how to disable WebRTC on Chrome in any other way?

 

I switched to the latest Chrome 43 beta version, hoping that I could disable it on chrome://flags.

Unfortunately that option is still grayed out, only available for Chrome android platform.

I use WebRTC Block on Iron (a Chrome based browser) and it works perfect !

You can test WebRTC leaks here.

Thanks OTT

 

I didn't know that. I'll give it a try.

Just downloaded Slimjet browser that allow WebRTC feature to be disabled on the security setting.

The reviews of this browser seems quite positive.

 

Regards,

WebRTC Block on  Iron, it still shows my IP. Checked with IPLEAK.

 

Slimjet WebRTC enable/disable feature works like a charms. Not quite sure I can get used to this browser though. So many features  :scratchhead:

 

Thanks all the same.

Strange, no leaks here on Iron... tested on different sites.

I'm using Iron portable v41.0.2200.0

I see 2 different internal IP's (VPN and real) which doesn't mather and 1 external IP, that of my VPN...

If a try WebRTC it doesn't work.

 

Do you surf in Incognito mode ? In that case make sure WebRTC Block is allowed to run !

Check "Allow in Incognito mode" on the "chrome://extensions/" page.

 

I tested Slimjet in the past and it is a very good and fast browser with indeed "to many" functions : Video downloader, Facebook integration, File upload... which I could not shut down permanently, after each update they were turned on again.

That was the reason for me to not use it further !

WebRTC Block is allowed in incognito, though the icon is not displaying on the toolbar.

 

http://lifehacker.com/how-to-see-if-your-vpn-is-leaking-your-ip-address-and-1685180082

 

http://ipleak.net/

 

Both the above webpages shows that Iron is leaking my IP.

Cyberghost (the link you gave me) give me a clear bill.

 

Shame as I like Iron. In the past Iron updates where far in between, things seems to have improved in this regard lately. 

 

I mostly use Firefox, just that some of the favorite websites I regularly use, like Weather Report, News and others essentials to me, do not display properly. Also I like watching TV series online and I found that flash player is crashing quite often.

 

Don't like IE, hence the need for Chrome.

 

Good that you reckon that Slimjet is a good browser. If it keep up with chromium latest release updates I'll try to get used to it.

 

Chrome should comes up with a fix for WebRTC, which apparently is on the pipeline and should be available on version 43.

So they say, I won't loose my sleep on account of it though. If Google really wanted they would have fixed it already, they did it for their android browser...

 

Cheers

It's normal that you don't see the icon.

 

On the links you propose I myself only see 2 internal IP's (real and VPN) and 1 external IP (VPN), so no leaks here.

Are you sure you not have the same and think that the (real) internal IP is a problem because that's not ?

To really have a leak you have to see 2 different external IP's.

 

Is the leaked IP between following ranges ?

10.0.0.0 - 10.255.255.255

169.254.0.0 - 169.254.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255

 

I have IPv6 turned off, could that have some influence ?

 

Did you try another VPN to make sure the VPN itself isn't the cause ?

Lucky you I guess.

In my case both my IP are leaking, Public and Private, positively, definitely.

I do not use IPv6, just IPv4.

And yes I just tried with ZenMate, same results. My other VPN is Browsec, both as browsers addons.

 

Uninstalled Slimjet, they advise that it may take up to 3 months before they may get up to speed with chromium latest version. Also funny way to update, requiring a download and reinstall of the new version.

FF is fine, most probably the issues with those webpages not properly displaying are due to my strict security/privacy settings. But I won't change that.

 

I'll use Chrome the least as possible until a fix is available.

192.168.0.0 - 192.168.255.255 (private)

122.151.164... (public)

 

Sorry OTT, missed this detail.on my previous reply.

There you have your answer (I think), these browser addons are not real VPN's, they are proxy-services.

That's the reason your IP is leaking !

 

Try a real VPN, "Google" for a Free VPN or check my Blog.

There are some reviews of Free/Trial VPN's on my Blog : Online Tips And Tricks

I'll give it a try and let you know shortly.

Though to be honest, Firefox allow for WebRTC to be disable and in FF there are no leaks. If it was due to the addons not being full VPN, the leak should be there on FF too. Originally, before disabling WebRTC from the settings I had WebRTC Block addon on FF and it didn't leak like it does on Chrome and Chromium browsers, but for Slimjet.

With Cyberghost installed, on Iron it still shows that it leak my private IP, and another that it is not of my public server IP.

 

Not the case with FF, no leaks there, IPLEAK.net shows a green button and advise, no leaks here. So does Lifehacker tool.

 

Unless IPLEAK and  Lifehacker are mistaken, as cyberghost tool do not detect any leak, at least my private IP is leaked on Iron.

 

You said only one IP is not a problem? Don't take it personally as I do appreciate very much your input, but I'll play it safe and use FF.

Indeed, internal IP's are leaked on Iron but I (and many others) agree this is not a security risk as long as you use a decent "real" VPN. If you don't trust this, you are right in using FF. Better safe than sorry !

 

I think the tools we use for checking differ, one checks just for WebRTC and the other checks for all leaks ?

That explains the different results between them and the different browsers...

Thanks for your help mate, much obliged.

 

By the way several reputable VPN providers, are warning their customers about this WebRTC IP leak and to use FF. That the function cannot be disabled in Chrome, only partially on Chrome for androids, also that the WebRTC Block Addon does not work on chrome any longer.

At the moment VPN seems to have come up with a fix, some tweaking that chromium base browser allow them to use. 

I guess that one has to purchase a full version of their product.

I'm really not an expert at all, I still type with one finger only  :blink:

 

The tool in Lifehacker page check for IP and ISP leaks.

 

IPLEAK.net is very comprehensive, checks for IP, ISP, DNS leaks and more.
