README

You can use these scripts to create your own IPv6 tunnel broker.

You need a dedicated OpenVPN account if your OpenVPN does not run as root. You must give this user full password-less sudo access to /sbin/ip: openvpn ALL=(ALL) NOPASSWD: /sbin/ip
You must enable package forwarding for IPv6. Either put sysctl -w net.ipv6.conf.all.forwarding=1 into you /etc/rc.local or appand net.ipv6.conf.all.forwarding = 1 to /etc/sysctl.conf. Warning: If you automatically receive your IPv6 routes, you must set your v6 routes manually (ip -6 route add ::/0 via <IPv6-Gateway> dev eth0!
You may need to activate Neighbor Discovery Proxy: Add net.ipv6.conf.all.proxy_ndp = 1 to your /etc/sysctl.conf
Copy the files client-connect-ipv6-broker.sh, client-disconnect-ipv6-broker.sh and ipv6-broker.sh to your server into the directory /etc/openvpn/ and make sure they are executable.
Append the lines from the server-ipv6.conf file to your OpenVPN server configuration.

You need a dedicated OpenVPN account if your OpenVPN does not run as root. You must give this user full password-less sudo access to /sbin/ip: openvpn ALL=(ALL) NOPASSWD: /sbin/ip
Copy the files up-ipv6-broker.sh, down-ipv6-broker.sh and ipv6-broker.sh to your client into the directory /etc/openvpn/ and make sure they are executable.
Append the lines from the client-ipv6.conf file to your OpenVPN client configuration.
