If you have Sygate Firewall and want to block port 135...
I have Sygate free.
After each set of entries click add
Try setting an "advanced rule" to block Port 135;
1. From Main Screen Select Menu's... {Tools} {Advanced Rules}.
2. Choose "Add" to create a new rule.
3. On General Tab:
Give rule a description
Choose "Block All Traffic"
Choose "Apply to all network interface cards"
Choose to Apply this rule during screen saver mode "Both on and off"
4. On Hosts Tab:
Choose to apply this rule to "All Addresses"
5. On Ports and Protocols tab:
Choose "TCP" as protocol.
Leave Remote port blank.
Type in "135" in the Local Port box.
Choose "Both" for traffic direction.
6. On Scheduling Tab:
Disable scheduling
7. On Applications tab:
Do not check any applications.
*When you have all the settings entered,click "ok" to create the rule.
