03007079e6 Improve VPN IPs
- Use %defaultroute and iptables MASQUERADE, no need to detect private IP
- Use %any for the first field of ipsec.secrets, instead of public IP
- As a result, the VPN server should now better adapt to IP changes.

261e472e3e Bugfix
- In xl2tpd version 1.3.8, which was pushed to the EPEL repository
  in Dec. 2016, the options "crtscts" and "lock" are no longer
  recognized in "/etc/ppp/options.xl2tpd" and generates an error.
- This commit fixes the VPN on CentOS by removing those options.
