[!INCLUDEsql-asdbmi] Replication over the Internet can provide flexibility, particularly for mobile Subscribers, but you must configure Internet replication appropriately to ensure adequate security. [!INCLUDEmsCoName] recommends using one of two techniques for securely sharing information over the Internet:
-
Virtual private network (VPN)
-
The Web synchronization option for merge replication
Virtual private networks provide a simple and secure layered approach to replicating [!INCLUDEssNoVersion] data over the Internet. The VPN connection over the Internet logically operates as a Wide Area Network (WAN) link between the sites.
This is achieved by allowing the user to tunnel through the Internet or another public network using a protocol such as [!INCLUDEmsCoName] Point-to-Point Tunneling Protocol (PPTP) available with the [!INCLUDEmsCoName] Windows NT version 4.0 or [!INCLUDEmsCoName] Windows 2000 operating system, or Layer Two Tunneling Protocol (L2TP) available with the Windows 2000 operating system. This process provides security and features similar to those available in a private network.
For more information about setting up a VPN, see the [!INCLUDEmsCoName] Windows documentation.
The web synchronization option for merge replication provides the ability to replicate data using the HTTPS protocol, which can be a convenient approach to replicating data through a firewall. For more information, see Configure Web Synchronization and Security Architecture for Web Synchronization.
