iSTAR eX Network Topology
iSTAR eX supports communications over 100Base-T and/or 10Base-T
Ethernet networks using TCP/IP.
Lan and Wan Configurations
The TCP/IP protocol transfers data across a number of networks. Because
iSTAR eX controllers use the TCP/IP protocol for network communications,
they can communicate with each other even when controllers are located on
different networks separated by other network platforms, as shown in
Figure 2.1.

Gateways and Firewalls
iSTAR eX 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.
