  1. The Teradata Vantage gateway processes each incoming IP address against the permissive filter deny element.
    1. The filter masks the incoming IP address under test with the mask from the deny element.
    2. The filter masks the IP address in the deny element with the same mask.
    3. If the two masked IP addresses match, the filter identifies the IP address under test as a candidate for denial. The filter then ends the deny phase of testing.
  2. The gateway tests for allow only if the tests for deny identifies an IP address as a candidate for denial. If allow-testing does not override the denial, the gateway rejects the IP.
    1. The filter masks the incoming IP address under test with the mask from the allow element.
    2. The filter masks the IP address in the deny element with the same mask.
    3. If the two masked IP addresses match, the filter allows the IP address under test to access the database and then ends the allow phase of testing.
