Timbuktu

Timbuktu Pro is remote control and file transfer software used to gain
access to Windows computers. The protocol uses TCP port 1417 and UDP
port 407. Add the Timbuktu service and allow incoming access from the
hosts on the Internet that need to gain access to internal Timbuktu
servers, and to the internal Timbuktu servers.
Timbuktu is not a particularly secure service and may compromise
network security. It allows traffic inside the firewall without
authentication. In addition, the Timbuktu server may be subject to denial
of service attacks. WatchGuard recommends using VPN options to
provide additional security.
