The ability to control the order of the Gateway list allows the PC-Duo Master user to control the order in which connections are attempted. The Host will automatically go down the list in order to establish a connection and report to a PC-Duo Gateway. If a connection attempt fails, the Host will automatically move to the next entry in the list; if a connection attempt succeeds, the Host will ignore all other entries in the list to that same PC-Duo Gateway and will proceed to the next PC-Duo Gateway entry. Since connection attempts occur automatically (and without notice to the PC-Duo Master user) and failures can take up to 30 seconds, it may be preferable to list the PC-Duo Gateway connections most likely to be available at the top of the list.
For example, a typical PC-Duo Gateway may have two entries in the Gateway tab: One with the internal IP address or DNS name when the Host is in the same network as the server (regular connection), and another with the external IP address or DNS name when the Host is outside the network (reverse connection). If a Host computer (for example, a laptop) is routinely moved in and out of the network with the PC-Duo Gateway (for example, from office to home and back), you may want to list the address which is used more often ahead of the one that is used less often.
