Subject: wireguard-functions.pl: Automatically skip IPv6 subnets
X-Git-Tag: v2.29-core197~25^2~49
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=68a3334413efb1a963b7cc6c6dca1ec0126e1cc1;p=ipfire-2.x.git

wireguard-functions.pl: Automatically skip IPv6 subnets

Since we do not support this and some VPN providers generate
configuration files that send any data over to them, we simply ignore
any IPv6 subnets.
