Learn how to <a href="https://gist.github.com/hwdsl2/123b886f29f4c689f531" target="_blank">enable multiple VPN users</a> with different credentials. For **Windows users**, a <a href="https://documentation.meraki.com/MX-Z/Client_VPN/Troubleshooting_Client_VPN#Windows_Error_809" target="_blank">one-time registry change</a> is required for connections to a VPN server behind NAT (e.g. Amazon EC2).
For Windows users, a <a href="https://documentation.meraki.com/MX-Z/Client_VPN/Troubleshooting_Client_VPN#Windows_Error_809" target="_blank">one-time registry change</a> is required for connections to a VPN server behind NAT (e.g. Amazon EC2). To support multiple VPN users with different credentials, just <a href="https://gist.github.com/hwdsl2/123b886f29f4c689f531" target="_blank">edit a few lines</a> in the scripts.
If using Amazon EC2, these ports must be open in the server's security group: **UDP ports 500 & 4500**, and **TCP port 22** (optional, for SSH). Clients are configured to use <a href="https://developers.google.com/speed/public-dns/" target="_blank">Google Public DNS</a> when the VPN connection is active. This setting is controlled by `ms-dns` in `/etc/ppp/options.xl2tpd`.
If using Amazon EC2, these ports must be open in the instance's security group: **UDP ports 500 & 4500**, and **TCP port 22** (optional, for SSH).
If your server uses a custom SSH port (not 22), or if you wish to allow other services through IPTables, be sure to edit the IPTables rules in the scripts before using.

The scripts will backup files `/etc/rc.local`, `/etc/sysctl.conf`, `/etc/iptables.rules` and `/etc/sysconfig/iptables` before overwriting them. Backups can be found under the same folder with .old suffix.
