I want to use WebRTC for firefox, but WebRTC also leak my private IP and public Internet IP. Can you provide a settings for only show private IP and WebRTC still work? Like Hide ALL IP ( http://www.hideallip.com ), it can only leak private IP, but public Internet IP hide, it's safe WebRTC. Some suggests? Thanks.

WebRTC offers encryption:

In the offer when the connection is first established with SDP see wiki an encryption method can be suggested. However the destination and source ips are in the headers. However using NAT gives your router a public ip, and keeps others private for indivifual devices. (Still not masked completely) However the standard is encrypted: []http://stackoverflow.com/questions/23085335/is-webrtc-traffic-over-turn-end-to-end-encrypted

Or are you asking about Firefox Hello?

Others always need to use your public IP address in order to make a successful connection. Using a proxy or private VPN service allows you to connect using a different public IP address than the one you were assigned by your internet service provider.

The recently publicized problem with WebRTC is that it could be used to learn other IP addresses, for example, the actual address assigned by your ISP, which could be used to locate you or associate your "anonymous" requests with your. For example: https://threatpost.com/webrtc-found-leaking-local-ip-addresses/110803 (describing some workarounds for Firefox users)

I don't know which services protect against that; I bet many of them claim to do so. However, you have to balance your desire for complete anonymity with the fact that your proxy/VPN service sees 100% of your web traffic. You need to REALLY trust them to sign up for that.
