Use internal and external Sametime Meeting servers to allow users within your organization to meet with external users from the Internet. One Sametime Meeting server is installed on the corporate intranet and another Sametime Meeting server is installed on another machine outside the firewall or in the network DMZ if you have one. DMZ, or "demilitarized zone," refers to an area of a network, usually between two firewalls, where users from the Internet are permitted limited access over a defined set of network ports and to predefined servers or hosts. A DMZ is used as a boundary between the Internet and your company's internal network.
Deploying meetings without a DMZ
When you set up two independent Meeting servers without a DMZ, the external Meeting server is not connected to your internal Meeting server. The room-based URLs are simpler with this configuration. Browser clients access the external server with anonymous logins. Each Meeting server is maintained separately.
Deploying meetings in a DMZ
The network DMZ is the only place on a corporate network where Internet users and internal users are allowed at the same time. When internal users are not allowed to address servers outside the corporate firewall, set up a reverse proxy that allows internal users to connect to the external Meeting Servers. The reverse proxy provides the routing services and allows a single entity to be configured in the firewall. It controls access to external servers and can be set up to limit usage.
