From 72fefd8269a55e1626fd00bad8cda908604f9325 Mon Sep 17 00:00:00 2001 From: Antonio Quartulli Date: Tue, 1 Nov 2022 22:43:46 +0100 Subject: openvpn: T3214: warn when setting nopool and server-ipv6 is being used Currently OpenVPN does not allow having an IPv6 subnet if 'nopool' was specified on the --server directive. For this eason warn if this specific configuration is being hit. This is probably something that should be fixed upstream, but for now we can't allow this combination of parameters.
