- SELinux in CentOS already has rules for both udp/1194 and tcp/1194,
so the protocol check was not needed.
- Remove unneeded arguments from some grep and rm commands.
Cleaner and better:
- Not relying in an external service
- Avoids a false positive when the server has multiple public IPv4
addresses and the user selects one which is not the default gateway
curl is always included with CentOS and wget is always included with
Debian/Ubuntu. So it was useless to install wget in CentOS like we were
doing for those cases when it wasn't already installed. Now curl will
be used instead.
Added 1.1.1.1 and removed two mostly unpopular choices.
Currently discarded services are: Yandex, Neustar, NTT, HE, Quad9 and
Freenom World. The list was starting to get too big.
Set EASYRSA_CRL_DAYS to 3650 instead of the default 180.
OpenVPN 2.4+ enforces the nextUpdate value in the CRL as a hard limit,
and will not work if more than 6 months passed since it was generated.
- Removed Debian 9 compatibility warning
- openvpn-blacklist is no longer uninstalled on removal
- Improvement: removal of /usr/share/doc/openvpn* hasn't been needed
for years
- Fixed: live iptables removal was failing for Debian since
6d51476047
This was long overdue for compatibility reasons. My decision to force
the upgrade now, has been made following recomendations published in
the OpenVPN 2.4 audit performed by Cryptography Engineering LLC.
- When FirewallD is detected, NAT is now applied via FirewallD instead
of iptables (fixes#267).
- iptables REJECT/DROP/ACCEPT rules where not being properly detected.
- iptables rules were applied even when FirewallD was detected and the
same rules were being applied via firewall-cmd.
