Opening Ports for Yahoo Messenger Voice Chat on the Trend Micro TrendMicroPC-cillinInternetSecurity Firewall
Open up Yahoo Messenger Voice Chat.
You might see a window pop up like the one above. If you do, click the
Allow button. If you try modifing the permissions for Yahoo Messenger Voice Chat with it open, you may get popup windows while trying to make your changes. So it's best to close Yahoo Messenger Voice Chat. Go ahead and do that now. Then go aheand and open up the Trend Micro PC-cillin Internet Security.
Click the
Personal Network & Firewall Controls button on the left hand side of this window.
Click the
Personal Firewall link. A window pane should drop down. Click the settings button in the window pane that dropped down.
Click the
Direct Internet Connection link. Then click the
Edit button.
Set the
Security level slider to Maximum or Medium. I prefer Maximum, because Medium allows file and printer sharing to be used by someone on the internet. Click the
Program Control tab at the top of the screen.
Find Yahoo Messenger Voice Chat in the list of applications displayed on this page, and click it to highlight it. Then click the
Edit button that is close to the top of the screen.
Delete all of the
In rules in the table at the bottom of the window
Click
Add button to add a new rule.
Click the
Ok button to save that rule.
Click the
Add button to add a new rule. Put a dot in the
Incomming radio button. Put a dot in the
Allow radio button.Use the Protocol
Type drop down box to select the protocol of the ports you are allowing. If you are unsure of the protocol of those ports just select the TCP/UDP option. Put a dot in to the
Specified Ports radio button. Then enter the ports to allow in to the
Specified Ports box. These ports can be entered in a list like 50,52,53 a range like 500-600 or a combination of both like 50,52,53,500-600. The IP Setting Type drop down box should be set to
All IP Addresses. Click the Ok button to save the rule.
Click the
Ok button all the way back to the main menu. It's very important to note, that if Yahoo Messenger Voice Chat tries to communcate on a port that you did not specify you will get another popup box asking to allow or deny that traffic. If you click allow, this firewall will create two new rules that will allow all traffic for Yahoo Messenger Voice Chat. The newly created rules will overide the specific rules that you created. Be absolutely sure you know what the program is doing before clicking that allow button.That should be it. The firewall should be properly configured.
To test if your port has been properly opened, you can use our Port Checker tool.
