Activating IP access protection

Dynamically expanding the IP access protection list with the firewall deactivated
If security is activated while the firewall is deactivated, there is no IP access protection. In
other words IP access in this device status is not restricted to the IP addresses entered in
the IP access protection list.
Nevertheless, even in this device status, it is possible to expand the list for IP access
protection dynamically if you have suitable user rights. As result of this action, the added
entries are displayed in STEP 7 special diagnostics. Access protection is, however, only
effective when the firewall is activated.
Solution:
Activate the firewall in the configuration. With this, the blocking of access for IP addresses
not entered in the list becomes effective.
