7.5 How to Control the Access to the SND Server
(TCP Port Access Control)
TCP Port Access
Control
You can control the access to the SND Server. To do so, various TCP
port types on the SND Server can be blocked. Network elements
with access rights can be defined as exceptions and excluded from
blocking. The SND Server only accepts data packets from network
elements defined as exceptions.
Security Levels
The port types to be blocked must be defined in the 'Security level'
area. The following categorization can be selected:
• Lock TCP access (locks TCP ports: HTTP/HTTPS...)
• 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 IP addresses or MAC addresses (hardware addresses) of the
network elements with access rights 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.
Test Mode
The 'test mode' allows you to check the configured access
protection. If the test mode is activated, access protection remains
active until the SND Server is rebooted. After restarting, the
protection is no longer effective.
