Works perfectly on my home network, took about 50ms to resolve.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

Need to pop back in here after reading some article, it is possible for website to get your local IP address, even if you are behind a NAT router or even if you are using VPN supposedly.

Using WebRTC and STUN.

This site correctly identified My public IP and my local, (behind router) IP

That link doesn't work in IE 11, it's only working in Firefox and Chrome. In IE it doesn't even display your public IP address because the STUN protocol isn't implemented at all.

Looks like a decent IPS will recognize and provide the ability to stop calls such as the one on that site.  I havent read the RFC referenced in the suricata log yet, but it is a different one than specified in the OP.

A dumb question because I'm not a network weenie.

I see the discussion above about WebRTC "leaking" IP addresses.  Would it be safe to say that only applies to web browsers?

Since this would most likely not be used in a browser, doesn't that make the point --while not unimportant-- moot?

 

Thanks,

I wouldn't know. I don't really do security. Sorry I can't help.
