Is there an API available to enable/disable Windows SP2 firewall on a given connection?

Ive read through the Windows SP2 Firewall API, but it seems there is no mean to do this, neither enabling nor disabling pop3, FTP serveretc on a given connection.

These properties are displayed in the Windows SP2 Firewall GUI under Network connection settings of the advanced tab! There were some methods to do this with ICS/ICF

Thanks!
