Highlighting the IP Security option and clicking the Properties button leads to the ability to turn off IPSec functionality or set it to one of three modes of varying aggressiveness, beginning with simply responding to requests for IP security, then progressing to requesting IP security, and finally to requiring it.
       The TCP/IP filtering option allows you to exercise quite a bit of control over which protocols are allowed to communicate with the computer. Filtering may be performed on any combination

of TCP and UDP port numbers and IP protocol number.
