iSTAR Ultra Network Topology
iSTAR Ultra supports communications over 10/100/1000 Mbps Ethernet networks using
TCP/IP.
LAN and WAN Configurations
The TCP/IP protocol transfers data across a number of networks. Because iSTAR Ultra
controllers use the TCP/IP protocol for network communications, they can communicate with
each other within a LAN or across a WAN, as shown in Figure 3-1.
Figure 3-1: Sample iSTAR Ultra Network
Gateways and Firewalls
iSTAR Ultra configurations provide access to remote C•CURE systems across firewalls and
Network Address Translators. This is because the master controller automatically accepts a
translated IP address if one is assigned from a remote host, or from an attached Network
Address Translator.
Generally, the TCP/IP ports, listed in Table 3-1 on page 3-2, must be open through a firewall.
