Private and Global Addresses
Note Network Security and Firewalls
Setting a global IP address for an EtherNet/IP Unit or built-in EtherNet/IP port
involves network security considerations. It is recommended that the user
contract with a communications company for a dedicated line, rather than
using a general line such as a broadband line. Also, be sure to consult with a
network specialist and consider security measures such as a firewall.
Once a firewall has been set up by a communications technician, on the other
hand, there may be some applications that cannot be used. Be sure to check
first with the communications technician.
• If the TCP port number (44818) or UDP port number (44818) that is used
for EtherNet/IP cannot be used if prohibited by a firewall in the communi-
cations path.
