Service Port overwrites Application default provided port (?)

[Martin2K]

Hello,

I would like to get a better understanding about the relationship Service vs Application when setting up FW rules:

Example:

"mysql" is provided with service TCP port 3306. 

If a rule is created using service TCP Port 58740 and in same rule under application "mysql" is added, would it cause the PA to associate application "mysql" with port 58740 system-wide. In other words, it would have a global effect on all rules using "mysql".

I would appreciate, if someone could shed some light on it.

Thanks,
