CPDBL is changing its name to OpenDBL. This makes sense since the project is going to support more than just Check Point gateways. Also, it is very important to note that on December 9th 2019, the cpdbp.net domain will be offline permanently. So make sure you are using the updated script well before then.
This is a really interesting project that is well worth looking at. It is an amazing demonstration of the power of Check Point’s API and dynamic objects. Remember though that you should always always always manually review any script that you download and run in your Check Point environment. You do not want to make the mistake of running something like the (soon to be) infamous “Common Check Point Commands.”
