Topic: WebRTC allowing sites to see your IP address through a VPN

I use a VPN and was worried when I saw this post in Lifehacker about "How to See If Your VPN Is Leaking Your IP Address"

the post comes down to something called WebRTC allowing websites to see your true IP address through a VPN connection

How to Test
1. turn off your VPN
2. go to a site like whatismyipaddress to see your IP address is
3. turn on your VPN
4. go to whatismyipaddress to see your new IP address is
5. go to the test website https://diafygi.github.io/webrtc-ips/ to see if your IP address from step 2 is shown

In Firefox and Chrome you can install extensions to disable WebRTC but I am unable to figure out how to do this with Epic.
