Configures how WebRTC's network traffic is routed by changing Chrome's privacy settings.

Image from store WebRTC Network Limiter
Description from store Configures the WebRTC traffic routing options in Chrome's privacy settings. ★ What it does: This configures WebRTC to not use certain IP addresses or protocols: - private IP addresses not visible to the public internet (e.g. addresses like - any public IP addresses associated with network interfaces that are not used for web traffic (e.g. an ISP-provided address, when browsing through a VPN) - Require WebRTC traffic to go through proxy servers as configured in Chrome. Since most of the proxy servers don't handle UDP, this effectively turns off UDP until UDP proxy support is available in Chrome and such proxies are widely deployed. When the extension is installed on Chrome versions prior to M48, WebRTC will only use the public IP address associated with the interface used for web traffic, typically the same addresses that are already provided to sites in browser HTTP requests. For Chrome version M48 and after, this extension provides one more configuration which allows WebRTC to use both the default public address and, for machines behind a NAT, the default private address which is associated with the public one. Said behavior will be the default after a fresh installation of the extension to Chrome M48. For upgrade scenarios, the previously selected configuration should not be changed. The extension may also disable non-proxied UDP, but this is not on by default and must be configured using the extension's Options page. ★ Notes: This extension may affect the performance of applications that use WebRTC for audio/video or real-time data communication. Because it limits the potential network paths and protocols, WebRTC may pick a path which results in significantly longer delay or lower quality (e.g. through a VPN) or use TCP only through proxy servers which is not ideal for real-time communication. We are attempting to determine how common this is. By installing this item, you agree to the Google Terms of Service and Privacy Policy at https://www.google.com/intl/en/policies/.

  • (2023-04-11) Vincent Y: Does not work. Private option says you need newer version of chrome but my chrome is already the newest. All the option will leak your ip address.
  • (2022-11-10) J.kevin M: its good
  • (2022-07-05) 陈宇: use my proxy server 不能点
  • (2022-05-28) finster baby: Just installed and when I tried to configure the options, the most important one to use a proxy was grayed out. The reason stated was because I needed a newer version of Chrome. Updated Chrome, and still the option is grayed out. My VPN was running, so I don't know what the deal is, but so far, this extension seems useless if I can't use a proxy. Will update my review if I can utilize the option.
  • (2022-02-23) Christopher Briggs: Does not work with "latest" version of chrome Version 98.0.4758.102. it says I need a newer version? I think this extension is toast.

  • (2021-08-25) Honoré SABATIER: Chrome use 50% of my uc when this extension is activated. I use this from years, not sure when it started to melt my computer.
  • (2021-08-21) Kelly Kane: This should just be baked into Chrome so that WebRTC honors proxy selections.
  • (2021-08-15) KingKoncorde (KingKoncorde): Using newest version chrome beta, the 'use my proxy server' option is greyed out. It says require newer version of chrome.
  • (2021-08-03) Igor: К сожалению уже данное расширение не работает на 92 версии, не тратьте время на его, воспользуйтесь альтернативой.
  • (2021-06-09) Generic General: Que mal :/ :/ :/ , ya no funciona para las nuevas versiones de Google Chrome. Era muy sencilla y práctica esta extensión, pero GOOGLE debe actualizarla para que vuelva a funcionar. ESTÁ SIN ACTUALIZAR DESDE LA FECHA: " 8 de enero de 2016 " . ALGÚN DESARROLLADOR DE GOOGLE DEBE ACTUALIZARLA
  • (2021-05-13) Катерина Тєрєхова 3-А: Не работает совершенно, а функция "Use my proxy server (if present)" даже не отвечает на клик, её нельзя даже выбрать.
  • (2021-05-11) Gerry P: It's no small wonder this extension doesn't work - IT HASN'T BEEN UPDATED SINCE 01/2016!!! I'm checking out WebRTC Network Limiter.
  • (2021-05-10) ADVIK SINGHAL: how to use ?
  • (2021-05-05) EBENEEZER SCROOGE: 05 MAY 2021 ... ... I am using it on BRAVE > Version 1.24.82 Chromium: 90.0.4430.93 (Official Build) (64-bit) The option to use the "Proxy" is grayed out. I am being told that is because it is due to CHROME being out of date >> "Grayed out options require newer version of Chrome." I am using the newest version of BRAVE, and it is up to date. Likely some difference between the GOOGLE version and the CHROME that BRAVE employs ... though I do not know that for sure. I ONLY use the browser ... I do not spend any time trying to know anything about it. Anyway ... any other experiences similar to this?
  • (2021-04-23) Yury Zhukov: Не работает. Последний пункт в параметрах не активен.
  • (2021-03-22) cir yxam: is not blocking webRTC leaking of internal IP# when using VPN, your privacy would be compromise when VPN is not blocking webRTC traffic, do your own proper tests by using these sites; https://browserleaks.com/webrtc https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/ [ click GATHER CANDIDATES button at page bottom, there should be no your local IP addresses reported ] remove extension & report ABUSE to google !!! keep in mind that google is MAKER of this extension !!!
  • (2021-02-14) x chu: ok,装上就把斗鱼上传给禁了
  • (2021-02-06) 天山童姥: The fourth option is not available, hope to fix it soon
  • (2021-02-05) Максим Б: Options "Use my proxy server" is disabled. Using latest (88.0.4324.150) chrome version in today. It worked in previous versions. I use the option, from chrome://flags/ #enable-webrtc-hide-local-ips-with-mdns
  • (2021-02-05) Peter K. (katarakt): Can't select the 4th option ("Use my proxy server"), as it's grayed out. The very last line in the extension options window states that "grayed out options require newer version of Chrome". I'm using the latest build - just checked and updated, the About page says it's up to date, but the 4th option is still grayed out. In essence, this extension seems to be broken and useless to me.
  • (2020-12-08) bo WU: 效果很好的插件
  • (2020-12-07) Andrew Allen: This may have worked in 2016, but they haven't updated this extension since then and in 2020 it just doesn't work. Don't waste your time.
  • (2020-11-19) SANWE: 成功屏蔽上传宽带占用,very nice~
  • (2020-10-20) 分享测试ShareTest: no works,,,sad
  • (2020-10-03) Валентин Владимирович: Всё арбайтен по стахановски. Выбрал самый нижний пункт. Всё отключилось. Вот этот: Use my proxy server (if present)
  • (2020-09-03) A**S S.barefar: بدنیست
  • (2020-08-05) zi ke: 实测无效
  • (2020-08-02) Mega Pixel: This plug in doesn't do what it meant, Be Aware!! The Only reason you might be interested in installing this plug in is to make your browsing safer and avoid less browser leaking which is not what I saw after testing (Regardless of which option you might choose on the plug in).
  • (2020-07-18) Paula Romero: muy buena
  • (2020-03-21) yuanlong Luo: 请问, 此扩展的选项页面为什么会不停的抖动???

  • (2019-12-11) sean pan: 很不错,隐私性提高了
  • (2019-12-09) Oleg: установил как VPN. сетевой адрес не меняет, блокировки не обходит.
  • (2019-12-08) Google User: Doesn't work, and complicated. A simple ON or OFF would suffice. Here are settings you must choose but no instructions on the benefits or risk associated: 1. Give me the best media experience: This option allows Chrome to explore all network paths to find the best way to send and receive media, which may be different from normal web traffic. 2. Use my default public and private IP addresses: This option forces Chrome to use the same network path for media as for normal web traffic, except when a web proxy is present. For machines behind a NAT, Chrome will also use the default private address to enhance connectivity. To prevent degraded performance, Chrome will attempt to send media directly instead of using the proxy. 3. Use only my default public IP address: This option is the same as Use my default public and private IP addresses except that Chrome will not use the private default address. 4. Use my proxy server (if present): This option forces Chrome to use the same network path for media as for normal web traffic, including use of a web proxy. Chrome will always attempt to send media through the proxy, which will typically hurt media performance and increase the load on the proxy; furthermore, this behavior may be incompatible with some applications.
  • (2019-11-25) shurmen 7: Не рекомендую -5. Установил. А запустить - у.й.х и до ПДЗы все пункты настроек! ))) При нажатии на него мышкой выдаёт стандартное "меню браузера" (параметр-х..яметры) "удалить и не показывать" ! При нажатии любой клавиши мышки! Такого г...на ещё не встречал....
  • (2019-10-22) I use a Good VPN and most Wed leak detectors showed no leaks but ONE IP leak program showed a partial leak of my local address. So i turned this extension on and selected the last option of force through proxy (for vpns) as some suggested here and the leak is now clear so this extension seems to do something. These web leaks things are sent outside of your vpn tunnel so some detectors cant see them but your ISP certainly will have a record so the vpn encrypted tunnel AND the web leak is critical to lock down. Apparently many quality VPN'S leak even when the tunnel is stable so what good is that for total privacy??
  • (2019-10-14) Senyo: ok
  • (2019-10-09) Pasquale Di Marzo: Non funziona
  • (2019-08-31) Summ Boddy: The solution to most people's issue with the extension is to select 'connect only through Proxy server' which is the default option selected despite being on the bottom of the list. Only select the other 3 if you value convenience over privacy and know what you are doing. If you select the first option on the list, you may as well not have the extension at all, I actually don't know why 'option 1' is even there because option 2 is certainly what you'd want to pick if you only want to leak WebRTC to sites that you trust to stream to-and-from. Option 3 is a truly skewed version of option 4. Option 3 will remove all streaming-speed benefits of webRTC leaking while preventing you from truly having an airtight protection of it because it will still leak partially, especially if the website is something where your microphone or webcam can be activated (even if you select no). This will enable your real IP to 'slip' despite offering 0% benefit. Never pick option 3 instead of option 4 if you are smart, both will protect you a good amount against leaks.
  • (2019-08-22) Empire Energy: Excellent!!! Update, not save settings (as for the 2nd photo)
  • (2019-08-16) Paul van Someren: Not neccessarily a review, more like a "Feature request". This extension is whitelisted, forced Installed and updated in our corporate environment using the latest Google Chrome .ADMX/ADML GroupPolicy Templates available (x64 bundle with each major release of Google Chrome). Currently, we are unable to configure this extension corporately as the chosen option is saved in the "secure preferences" file in the user's Google Chrome profile. This file contains hashing to prevent tampering. In an attempt to add or modify settings, the file becomes "corrupt" and is reset to it's default. Please, add a feature to this extension, which makes it possible to pre-configure this extension for corporate users using the registry (separate WebRTC GroupPolicy .ADMX/ADML template.)
  • (2019-07-27) Nothing Personal: Не работает! Хоть какие настройки ставьте, хоть что отмечайте, ничего не отключает и не скрывает. Абсолютно бесполезное. А кто пишет, что у них там якобы что то скрыло, те просто не знают что такое WebRTC
