So. here we go :-) Patch (for 2.3.3, but should apply as well to master) is appended. Windows installers for x32 and x64 can be found here: http://www.greenie.net/ipv6/openvpn-install-2.3.3-routefix-I099-i686.exe http://www.greenie.net/ipv6/openvpn-install-2.3.3-routefix-I099-x86_64.exe Please test, and report if that fixes it for you. The sources in there are "pristine 2.3.3 plus the appended patch", built with pkcs11-helper 1.11 and openssl 1.0.1g. gert -- USENET is *not* the non-clickable part of WWW! //www.muc.de/~gert/ Gert Doering - Munich, Germany g...@greenie.muc.de fax: +49-89-35655025 g...@net.informatik.tu-muenchen.de

Subject: [PATCH] IPv6 route delete fix for Win8
Use "store=active" for IPv6 route deletion as well - seems to be required
on Windows 8 and up, and will break OpenVPN reconnection, as old routes
are not properly deleted, thus new routes cannot be added.
