Sorry, but that's a two-way street, buddy. The same can be said for people who bought Untangle, and are stuck with dealing with the fact that it only supports OpenVPN, and no other industry standard VPN.
Those of us who implemented Untangle for free, and later discovered we needed something other than OpenVPN, may not have quite the financial investment, but we do have an significant investment in time, resources, and frustration. Thanks for blowing us off. Shows how much you don't really give a crap.
