Enable IPSec on a Network Adapter

Enables IP security for a network adapter. In this script, all TCP and UDP ports as well as all IP protocols are allowed; hence the value 0 is passed to the EnableIPSec method in each case. If only specific ports or protocols are allowed, these should be passed in the form of arrays.
