Open up Point-to-Point Tunneling Protocol.
You might see a window pop up like the one above. If you do, put a dot in to the Allow all activities for this application radio button, and click the Ok button. If you try modifing the permissions for Point-to-Point Tunneling Protocol with it open, you will get popup windows while trying to make your changes. So it's best to close Point-to-Point Tunneling Protocol. Go ahead and do that now. Then go aheand and open up BitDefender Internet Security v10.
Click the Firewall button on the left hand side of the window.
Now click the Traffic link close to the top of the window.
We break the outgoing traffic and incoming traffic guides in to two parts, when you are done here make sure you follow the outgoing guide as well.
Find Point-to-Point Tunneling Protocol in the list of programs. Right click that rule and select Edit Rule. You may need to add additional new rules, if we show you more configurations than your firewall currently has for Point-to-Point Tunneling Protocol. If you do, then just select Add Rule instead of edit rule. Be sure to configure or delete all the existing rules before adding a new one.
Create persistant rule
Click the Ok button to save that rule. You should now be back at the Current Profile Settings window.
Set the Select application: drop down box to Path/Filename. Make sure the full path to the program you are opening ports for appears in the Program Path: box. Set the Action drop down box to allow. The Direction drop down box should be set to Inbound. Use the Protocol drop down box to select the protocol of the ports you are opening. The software manufacturer would be the one to list what protocol and ports you need to open. Leave the Source Address section alone. We are going to make some changes to the Destination Address section. Use the Type drop down box to select Host. The IP Address drop down box should be set to Any. Make sure the Local checkbox is checked. If you want to open a single port set the Ports drop down box to Specific. Then enter the port number to open in to the No. box. If you want to open a range of ports, set the Ports drop down box to Range. Enter the lowest port number of that range in to the From: box. Then enter the highest port number of that range in to the To: box.
That should be it. The firewall should be properly configured. I had to restart my computer, before the new rules took affect. So you might want to try that as well.
To test if your port has been properly opened, you can use our Port Checker tool.
