# Design # Network Ports used for communication ### Introduction This drawing should give you an overview of the used R80 and R77 ports respectively communication flows. It should give you an overview of how different Check Point modules communicate with each other. Furthermore, services that are used for firewall operation are also considered. These firewall services are also partially mapped as implied rules in the set on the firewall. #### Link Thank you Heiko Ankenbrand for creating such a valuable overview: [https://www.ankenbrand24.de/index.php/articles/check-point-articel/arcitecture/r80-communication-ports/](https://www.ankenbrand24.de/index.php/articles/check-point-articel/arcitecture/r80-communication-ports/) ### Overview [![http://www.ankenbrand24.de/wp-content/uploads/2019/03/ports.png](http://www.ankenbrand24.de/wp-content/uploads/2019/03/ports.png)](https://www.ankenbrand24.de/wp-content/uploads/2019/12/Ports_1.5a.pdf) ### Download [https://www.ankenbrand24.de/wp-content/uploads/2019/12/Ports\_1.5a.pdf](https://www.ankenbrand24.de/wp-content/uploads/2019/12/Ports_1.5a.pdf) # Log Files location Check Point Here are the different Log File locations on a Check Point Appliance:
