- Upgrade to easy-rsa 3.0.0
- Firewall support: rules are added for both FirewallD and iptables if
needed.
- Creation of our own configuration files for both the server and
clients.
- Using subnet topology instead of the deprecated net30.
- Removed port 53 question during install: user can just choose that
port during setup.
- Removed internal networking option: this is a road warrior installer
after all.
- Bugfix: the default easy-rsa directory was not correctly deleted if
one was already there.
