OpenConnect is known to work, with both IPv6 and Legacy IP, on Linux(includingAndroid), OpenBSD, FreeBSD (including Debian GNU/kFreeBSD), NetBSD,DragonFly BSD, OpenIndiana/OpenSolaris, Solaris 10/11, Windows and Mac OS X platforms, and should be trivially portable to any other platformsupporting TUN/TAP devicesand on which GnuTLS orOpenSSL runs.
For Solaris support, and for IPv6 on any platform, thevpnc-script shipped with vpnc itself (as of v0.5.3)is not sufficient. It is necessary to use the script from the vpnc-scriptsrepository instead. That repository also contains an updated version ofvpnc-script-win.js which is required for correct IPv6 configurationunder Windows.
OpenConnect is known to work on at least i386, x86_64, PowerPC and MIPSprocessors, and should not have issues with portability to other CPUs.
