Default Firewall with more rules than open / closed ports

Is there a recommended way to add more advanced firewall rules to a standard ISPconfig3 system?

For example in some cases I'd like to close port X with exceptions for some allowed IPs.

Is there a recommended way to add such custom rules without ISPconfig 3 overwriting them?
