About Firewalls

A firewall is a software or hardware combination which protects a local network from unwanted access to or from the "outside" (typically the Internet). Usually, a firewall will block most TCP/IP communications, but permit certain kinds, such as Web access. Firewall protection is often combined with special "proxy server" software whose job it is to relay the permitted traffic between the local network and the outside world, and vice versa.

If your network is protected by a firewall or proxy server, you will not be able to freely send messages to and from the Internet for three reasons:

  1. The firewall may be blocking TurboNote traffic (until you explicitly "open" a channel for it on TurboNote's IANA registered ports of 39681and 34249)
  2. The computers in your local network only have indirect access to the Internet, because they depend on the proxy server to relay the appropriate Internet traffic. That is, a local computer cannot directly "see" (e.g. "ping") computers which are directly attached to the Internet. If it cannot communicate directly with them, it cannot send them a TurboNote.
  3. The computers in your local network will not have identities or IP addresses which are known to the computers on the Internet. These identities are what TurboNote+ uses to send messages.

Resolving the first issue simply requires the correct firewall configuration. TurboNote Relay Server is specifically designed to solve the remaining issues, with additional benefits such as automatic note queuing, activity logging, close control of who can send what content, and so on.
