Here is the latest pre-1.3.2 beta that now supports IPv6 over tun on Linux. Please test. I plan to release 1.3.2 shortly if there are no problems reported.
Download from CVS or http://openvpn.sourceforge.net/beta/openvpn-1.3.1.7.tar.gz Change Log: * Added SSL_CTX_set_client_CA_list call to follow the canonical form for TLS initialization recommended by the OpenSSL docs. This change allows better support for intermediate CAs and has no impact on security. * Added build-inter script to easy-rsa package, to facilitate the generation of intermediate CAs. * Ported to NetBSD (Dimitri Goldin). * Fixed minor bug in easy-rsa/sign-req. It refers to openssl.cnf file, instead of $KEY_CONFIG, like all other scripts (Ernesto Baschny). * Added --days 3650 to the root CA generation command in the HOWTO to override the woefully small 30 day default (Dominik 'Aeneas' Schnitzer). * Fixed bug where --ping-restart would sometimes not re-resolve remote DNS hostname. * Added --tun-ipv6 option and related infrastructure support for IPv6 over tun. * Added IPv6 over tun support for Linux (Aaron Sethman). * Added "Important Note on the use of commercial certificate authorities (CAs) with OpenVPN" to HOWTO based on issues raised on the openvpn-users list.
