VPN
You can set up a Virtual Private Network (VPN) using Mac OS X Server.
VPN is a network transmission protocol that uses encryption and other technologies to provide secure communications over a public network. Typically the public network is the Internet, but VPNs are also used to support connections between multiple intranets within the same organization and to join networks between two organizations to form an extranet.
VPNs transmit encrypted IP packets so that only legitimate targets can interpret them, protecting the contents of messages from network sniffing. Mac OS X Server lets you set up and manage VPN policies that support different authentication and authorization options and network connection attributes.
Mac OS X Server’s VPN service serves Mac OS X, Windows, and UNIX clients and supports strong authentication using
IP Failover
You can configure IP failover to help maximize server availability.
IP failover is a way to set up a standby server that will take over if the primary server fails. The standby server takes over the IP address of the failed server, which takes the IP address back when it is online again. IP failover is useful for DNS servers, web servers hosting websites, media broadcast servers, and other servers that require minimal data replication.

You can deliver live and prerecorded media over the Internet to both Macintosh and Windows users, or relay streamed media to other streaming servers. You can provide unicast streaming, which sends one stream to each individual client, or multicast streaming, which sends the stream to a group of clients.
