Getting OpenVPN to work when ipv6 support is missing
You may get error messages such as:
"GDG6: NLMSG_ERROR: error Operation not supported"
"GDG6: remote_host_ipv6=n/a"
If it cannot get ipv6 connection, add these to your config file:
pull-filter ignore "route-ipv6" pull-filter ignore "ifconfig-ipv6"
