IPV6 error

[warezdown 0]

Hello
I have ipv6 disable on my arch through sysctl option.

I have set

Quote

pull-filter ignore "route-ipv6"
pull-filter ignore "ifconfig-ipv6"

in my airvpn.conf.

Despite this openvpn is trying to add IPV6 route, therefore it populates my syslog with errors

it looks like ignore option "route-ipv6" is not taken into account by openvpn.

What do you thnk ?

Thanks

In the config, remove --push-peer-info and --setenv UV_IPV6 yes, or set the latter to no. Then remove the --pull-filters.

Also be advised, Arch does not read /etc/sysctl.conf. All values must be written in some conf in /usr/lib/sysctl.d/*.conf or /etc/sysctl.d/*.conf (/etc takes precedence), where Systemd picks them up and applies them at boot.
