Networks & Firewalls

For MTP/IP applications to communicate between computers, each must be connected by an Internet Protocol (IP) network path.  The remote system must be running an MTP/IP application, such as ExpeDat, SyncDat, HyperGate, or one of the enclosed Utilities.  If there are firewalls, VPNs, or NAT devices between the computers, then these devices must be configured to allow traffic on the appropriate UDP/IP ports.

Typical MTP/IP installations use UDP/IP ports in the range of 8080 to 8089.  The MTP Utilities also use TCP/IP ports in that range.  However, each MTP/IP application can be configured to use any available port numbers.  Should you experience difficulty communicating with a remote MTP/IP system, check with your network administrator to make sure you are using the correct ports.

Additional information about configuring firewalls can be found in DEI Tech Note 0002.

Note that MTP Utilities use both TCP and UDP ports 8082 by default.
