When you established the VPN server, you must configure a DHCP server to designate addresses to customers, or you can create a bank of IP addresses to appoint to clients straight from the VPN server.

If this alternative is picked and the reliable remote access policy is set to enable remote access, the user will be able to connect to the VPN.
