Cable modems are designed to be able to do filtering on the basis of TCP/UDP port numbers and also on some aspects of the underlying MAC layer addressing. The cable modems are configured to do this at boot-time by the configuration file they fetch from the ISP.

However, IPSec is not one of the blocked protocols.
