Welcome

Port Test allows you to see if a TCP port on your computer is accessible over the Internet. Many programs and services require you to have open ports to use them properly, for example BitTorrent clients and FTP servers.

For Port Test to determine if your TCP port is open there must be an active listener, i.e. the program/service you are opening ports for must be running. If a port is inacccessible it is usually either a firewall setting or an ISP restriction.
