2.11.2 Setting up firewalls
Firewall between the Internet gateway and the Internet
Configure the firewall between the Internet gateway and the Internet to allow inbound communication from the Internet to the DMZ so that data can pass through the host set with Host Name or IP address and the port set with Port Number (which you can set by opening the Agent Configurations view of the Settings module, and under Basic settings, selecting Internet Connection Settings, and then Internet Gateway).
Firewall between the Internet gateway and the management server or Remote Installation Manager
Configure the firewall between the Internet gateway and the management server or Remote Installation Manager to allow inbound communication from the DMZ to the internal network so that data can pass through the port used for communication with the management server and Remote Installation Manager. For details, see A.1 Port number list.
