Problem with Punk Buster (Firewall)

By default, Windows Firewall with Advanced Security blocks all unsolicited inbound network traffic, and allows all outbound network traffic. For unsolicited inbound network traffic to reach your computer, you must create an allow rule to permit that type of network traffic. If a network program cannot get access, verify that in the Windows Firewall with Advanced Security snap-in there is an active allow rule for the current profile. To verify that there is an active allow rule, double-click Monitoring and then click Firewall .If there is no active allow rule for the program, go to the Inbound Rules node and create a new rule for that program. Create either a program rule, or a service rule, or search for a group that applies to the feature and make sure all the rules in the group are enabled.

To permit the traffic, you must create a rule for the program that needs to listen for that traffic. If you know the TCP or UDP port numbers required by the program, you can additionally restrict the rule to only those ports, reducing the vulnerability of opening up all ports for the program.

To add an inbound rule for a program by using the Windows Firewall Control Panel program

1. Click Start, click Control Panel, and then under Security, click Allow a program through Windows Firewall.

2. On the Exceptions tab, check the list to see if an exception for your program already exists and just needs to be enabled. If you find one, select the box next to it, and then click OK.

3. If a rule does not already exist, click Add program.

4. In the Add a Program dialog box, either select your program from the list, or click the Browse button to enter the path to the executable file.

If the program should only be accessed from certain network addresses, click Change Scope, and enter the appropriate subnet addresses or individual IP addresses. 

5. Click OK to return to the Add a Program dialog box.

6. Click OK to return to the Windows Firewall Settings dialog box. Your new exception is displayed in the list in alphabetical order with a check mark in the box next to it. Click OK to save your new exception rule.

7. Test your rule by running the network program that needs to be able to receive unsolicited network traffic.

Hope it helps!
