Bullard" , openvpn-devel Gert, Without invalidating the reason for your frustration, I am breathing a sigh= of relief. As a complete aside, in some ways ipv4 is actually more useful to me in my = work. In a private network I can tell where in the network the traffic is c= oming from. Even on the internet I can tell country, ISP etc. Very useful f= or security ACLs etc. Unless I=E2=80=99m completely mistaken, I don=E2=80= =99t believe this is easily done in ipv6.=20 BTW, a big thank-you to you and all the devs in the OpenVPN project!
