5.2 How to Control the Access to the TPG (TCP Port
Access Control)
TCP
Port Access Control
You can control the access to the TPG. To do so, various TCP port types
on the TPG can be locked. Network elements with access rights can be
defined as exceptions and excluded from blocking. The TPG 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:
