You can disable multiple services simultaneously.

6Click Submit.

The selected service(s) are removed from the list. The list reappears. To return to the Configuration menu, click Configuration at the top of the page.

Blocking outgoing services

By default, the security stance of the SOHO is to allow all outgoing packets from computers on the private network protected by the SOHO firewall to the Internet. You can, however, selectively close your network to certain types of Internet connectivity. For example, one way to prevent users behind your firewall from transferring unsafe files from the Internet to the private network is to block all outgoing FTP.

It is important to remember that each service you block reduces accessibility to the files and destinations on the Internet. Again, this is representative of the inherent trade-off between access and security.

Blocking a TCP or UDP service

The two most commonly used network protocols are TCP and UDP. You can choose to block outgoing TCP or UDP traffic by port number or range.
