Generic Discovery Protocol - GDP
The GDP service is a protocol developed by Qbik New Zealand for 'finding' or 'discovering' Internet connectivity servers (such as WinGate). It is used by both the WinGate Internet Client (WGIC) and GateKeeper for finding WinGate. Once installed, GDP can be left unattended. It is designed to be fully automatic, requiring no user intervention.
The GDP service listens to the system port 368 for broadcast messages sent out by clients. When the WGIC is running on client computers, it broadcasts a 'discover' request to locate WinGate servers. These are listed in the WinGate Internet Client control panel app.
GDP Guidelines:
- You only need one GDP service
- It must be on port 368
- GDP is required for the WRP clients to automatically find WinGate
- GDP should only be bound to your internal LAN adapter/s
- Generic Discovery Protocol is sometimes called Gateway Discovery Protocol
