Port Blocker

Port Blocker allows the selective enabling and disabling of ports. This can restrict or allow the use of certain applications such as email, peer-to-peer music sharing and instant messenger chat. By default Port Blocker allows all ports.

Note: Port Blocker is not a firewall. NetPurifier is designed to sit inside the trusted network. It will block ports to and from the firewall to control application access but is not designed to protect the network from outside factors.
