Installing and Starting the Ethernet CP with STEP 7

IP Access Protection Tab

Using IP access protection gives you the opportunity of restricting communication over the CP of the local S7 station to partners with specific IP addresses. Partners

V5.2.1 you have not authorized cannot access data of the S7 station over the CP using the IP protocol.

In this tab, you can activate or deactivate IP access protection and can enter IP addresses in an IP access control list (IP-ACL).

As default, IP access protection is deactivated.

SIP access protection for configured connections with specified partners

If you want to restrict access to the precise set of partners you specify during connection configuration, you simply need to activate access protection. In this case, you do not need to enter IP addresses in list.

Remember, however, on unspecified connections, all other IP addresses are unauthorized and are rejected.

IP access protection relates to all connection types handled using the IP protocol (TCP, ISO-on-TCP, UDP)

SIP access protection for partners with specific IP addresses

To allow IP access for specific IP addresses, enter these IP addresses in the IP access control list.

The IP addresses you specify when you configure the connection always belong to the permitted IP addresses and do not, therefore, need to be entered explicitly in the IP-ACL.
