Firewall Rules

This section provides a comprehensive list of the firewall rules involved in Edge Server deployments and what features require each of the ports. It also discusses which direction the connections take so that the appropriate ports can be opened inbound or outbound. In some scenarios, the Edge Server initiates the outbound connection to external destinations.

The Access Edge Server is the core of any remote access. At a minimum, remote user access must be allowed to the Access Edge Server to support any kind of web conferencing or A/V traffic. Table 27.1 displays the firewall requirements for traffic between the Internet and the Access Edge Server IP addresses.
