Click OK button on all opened windows. With this, you will filter almost all ports, without interrupting any application which are using this ports.
For example: If you don't add 5190 port in TCP ports, will no produce any conflict with ICQ communication.
In some computer configurations, TCP/IP filtering can make some problems like Internet interruption or stop working of some internet applications. If you see some problems like described, its better to stop TCP/IP filtering.
Please note, that if you are using some router or wireless access point probably this settings for port filtering have to be made from router control panel. Or if you are in office network may be your system administrator has been already done this.
