Public Addresses#

By default, NAT is used and RFC 1918 addresses are assigned to the clients for IPv4 and RFC 4193 addresses for IPv6.

In case you want to use routable IPv4 and/or IPv6 addresses you need to modify the configuration and make sure your upstream router routes the appropriate range(s) to your VPN server’s IP address(es).

First edit /etc/vpn-server-api/config.php and set the range and/or range6 addresses as appropriate.

Next, modify the firewall according to these instructions.

To apply the configuration changes:

$ sudo vpn-maint-apply-changes

If the command is not available, install the vpn-maint-scripts package first.
