Grant or restrict network access

You can restrict access to the local host or to the machines on the access list, or grant access to all machines. The access list is a comma-separated list of IP numbers of the machines that must have access.

Restricting access to the local host only works if requests are submitted from the same machine that KCM Core runs on.

  1. Start KCM Core Administrator.

    If jobs are submitted through KCM Contract Manager, the servers hosting KCM Contract Managers must be granted access to this interface.

  2. In the tree view, click the KCM Core node.
  3. In the right pane, select the DP Manager tab.
  4. Locate the TCP/IP Interface section and make a selection under Security.

    • To restrict access to the local host, select Access is restricted to the local host.

    • To allow access to all machines, select No access restrictions.

    • To grant access to particular machines, select Network access list and specify the IP numbers in the corresponding field.

      Example 10.0.0.0/24

      This setting grants access to IP numbers in the range from 10.0.0.0 to 10.0.0.255.

  5. Click Save & Apply.
