The Teradata Database requires that any security and privacy required for network communication is provided using IPSEC on both z/OS and the Teradata Database. Specifically, in the z/OS IP stack being used by TDP, both TCP traffic to and from the network port used by the Teradata Database, whose default is 64432, and UDP traffic to and from the dynamically defined network port used by the Teradata Database use IPSEC. The IPSEC specifics defined on z/OS must mirror the specifics defined on the Teradata Database. For more information about z/OS IPSEC, see the IBM z/OS Communications Server: IP Configuration Guide and z/OS Communications Server: IP System Administrator's Commands, available at: http://www-01.ibm.com/support/knowledgecenter/.
