Firewall Replication
Replicator supports one way and bidirectional replication between any pair of web applications where one of the web applications can communicate with the other using HTTP or HTTPS. In a firewalled environment, one of the web applications is behind a firewall and cannot be accessed by the other web application. Replicator requires that the web application behind the firewall must be able to communicate with the other.
Configuring Replicator for firewalled replication is almost the same as configuring non-firewalled replication. The only change is how you configure your Replication Connections between web applications. This article describes the steps you must perform to configure Metalogix Replicator for firewalled replication.
Operationally, Replicator changes its behavior in firewalled replication environments. Since only the web application inside the firewall can communicate with the other, its instance of Replicator manages all communication and transfers for replication. Instead of the Replicator instance outside of the firewall downloading packages from the web application inside the firewall, the Replicator instance inside the firewall uploads packages to the instance outside the firewall using BITS Server Extensions.
The following sections describe the tasks you must perform on each server running the SharePoint Web Application service, including all web front-end servers. These steps can be performed before or after installing Replicator.
1.For each web application server in the farm outside the firewall, install BITS IIS Server Extension. For instructions, see http://technet.microsoft.com/en-us/library/cc753301.aspx.
2.For each web application server in the farm outside the firewall, install IIS Hotfix 2587894 from http://support.microsoft.com/kb/2587894.
