The firewall rules in this section are samples that were constructed on
a single workstation firewall (Symantec Desktop Firewall). They demonstrate
the use of block rules and permit rules:

workstation is prevented.
- The permit rules allow the workstation to interact with Foreign File System
(file I/O and ENQ/DEQ) while leaving the block rules to prevent other network
access. (As stated, the block rules prevent use of TSO Commands
and Remote Debug.)
The following examples show firewall rule definitions:
