Recently I tried to find a VPN providers who fully supported IPv6. There were only few options and they were much on the expensive side. Of the remaining IPv4 VPNs only few warned you in their docs about switching off IPv6, even fewer switched it off while running, and one I'm aware of switched it off forever in a sneaky way on Windows that involved continuously overwriting registry keys, which on the one hand was laudably paranoid but on the other hand caused endless hours of troubleshooting for me. In a nutshell, if your computer has a IPv6 address as it should have, the software from most commercial VPN providers will leak your IPv6 IP all the time to all websites and make you easy to identify. I suppose this is well-known to savvy users and sysadmins, but still thought it worth mentioning in the context if this more general router vulnerability. Some of the cheaper VPN services out there are very insecure anyway.
