Welcome to the forums, kaiaphas

Have you looked at the FAQs in https://forums.comodo.com/frequently_asked_questions_faq_for_comodo_firewall-b32.0/ to see if there is any useful guidance there?

If you know the port numbers and protocols involved, then setting up the corresponding CFP rules should be fairly straightforward.
