+IPv6 transport support
+----------------------
+
+[ Last updated: 25-Mar-2011. ]
+
+OpenVPN-2.1 over UDP6/TCP6 README for ipv6-0.4.x patch releases:
+( --udp6 and --tcp6-{client,server} )
+
+* Availability
+ Source code under GPLv2 from http://github.com/jjo/openvpn-ipv6
+
+ Distro ready repos/packages:
+ o Debian sid official repo, by Alberto Gonzalez Iniesta,
+ starting from openvpn_2.1~rc20-2
+ o Gentoo official portage tree, by Marcel Pennewiss:
+ - https://bugs.gentoo.org/show_bug.cgi?id=287896
+ o Ubuntu package, by Bernhard Schmidt:
+ - https://launchpad.net/~berni/+archive/ipv6/+packages
+ o Freetz.org, milestone freetz-1.2
+ - http://trac.freetz.org/milestone/freetz-1.2
+
+* Status:
+ o OK:
+ - upd6,tcp6: GNU/Linux, win32, openbsd-4.7, freebsd-8.1
+ - udp4->upd6,tcp4->tcp6 (ipv4/6 mapped): GNU/Linux
+ (gives a warning on local!=remote proto matching)
+ o NOT:
+ - win32: tcp4->tcp6 (ipv4/6 mapped) fails w/connection refused
+ o NOT tested:
+ - mgmt console
+
+* Build setup:
+ ./configure --enable-ipv6 (by default)
+
+* Usage:
+ For IPv6 just specify "-p upd6" an proper IPv6 hostnames, adapting the example
+ from man page ...
+
+ On may:
+ openvpn --proto udp6 --remote <june_IPv6_addr> --dev tun1 \
+ --ifconfig 10.4.0.1 10.4.0.2 --verb 5 --secret key
+
+ On june:
+ openvpn --proto udp6 --remote <may_IPv6_addr> --dev tun1 \
+ --ifconfig 10.4.0.2 10.4.0.1 --verb 5 --secret key
+
+ Same for --proto tcp6-client, tcp6-server.
+
+* Main code changes summary:
+ - socket.h: New struct openvpn_sockaddr type that holds sockaddrs and pktinfo,
+ (here I omitted #ifdef USE_PF_xxxx, see socket.h )
+
+ struct openvpn_sockaddr {
+ union {
+ struct sockaddr sa;
+ struct sockaddr_in in;
+ struct sockaddr_in6 in6;
+ } addr;
+ };
+
+ struct link_socket_addr
+ {
+ struct openvpn_sockaddr local;
+ struct openvpn_sockaddr remote;
+ struct openvpn_sockaddr actual;
+ };
+
+ PRO: allows simple type overloading: local.addr.sa, local.addr.in, local.addr.in6 ... etc
+ (also local.pi.in and local.pi.in6)
+
+ - several function prototypes moved from sockaddr_in to openvpn_sockaddr
+ - several new sockaddr functions needed to "generalize" AF_xxxx operations:
+ addr_copy(), addr_zero(), ...etc
+ proto_is_udp(), proto_is_dgram(), proto_is_net()
