RealPresence DMA Edge Considerations

The RealPresence DMA Edge system is Polycom’s firewall traversal solution for both SIP and H.323 environments. It has the following specific requirements:

  • Network Location. It must be connected to the DMZ.
  • Network Interface Card. The RealPresence DMA Edge system must have four network interface cards (NICs) defined on the virtual machine. Even if the RealPresence DMA Edge system’s network interfaces are configured so that some NICs remain unused, the NICS should NOT be removed.
