6.3 How to Control Access to the UTN Server (TCP
Port Access Control)
TCP
Port Access Control
You can control the access to the UTN server. To do so, various TCP
port types on the UTN server can be locked. Network elements that
have permission to access the UTN server, can be defined as
exceptions and excluded from locking. The UTN server only accepts
data packets from network elements defined as exceptions.
Security Levels
The port types to be locked must be defined in the 'Security level'
area. The following categorization can be selected:
• Lock UTN access (locks UTN ports)
• Lock TCP access (locks TCP ports: HTTP/HTTPS/UTN)
• Lock all (locks IP ports)
Exceptions
In order to exclude network elements (e.g. clients, DNS server, SNTP
server) from port locking, they must be defined as exceptions. To do so,
the access-authorized network elements’ IP addresses or MAC
addresses (hardware addresses) must be entered in the 'Exceptions'
area. Please note:
• MAC addresses are not delivered through routers!
• The use of wildcards (*) allows you to define subnetworks.
