Happy to see IPv6 support is working in VRS as I stumbled upon it working by accident.
My client used it by default as I have it setup and working on my network and I was curious why I wasn't seeing all the options. Seems I was considered an "internet" user and got those options.
Unlike IPv4 VRS doesn't seem to recognize IPv6 connections as local in the same way yet.
Something for the future.
IPv6 Local
Re: IPv6 Local
When my ISP supports IPv6 I'll add support for it
Until then I've no practical way of testing anything that gets added for that. The current IPv6 support is all .NET, I don't have any code in there for distinguishing between local and Internet clients over IPv6.

Re: IPv6 Local
My ISP doesn't support IPv6 either. I just run a tunnel to an IPv6 broker.
