## Detailed Description

Middleman between UDPProxyServer and UDPProxyClient, maintaining a list of UDPProxyServer, and managing state for clients to find an available forwarding server.

When NAT Punchthrough fails, it is possible to use a non-NAT system to forward messages from us to the recipient, and vice-versa The class to forward messages is UDPForwarder, and it is triggered over the network via the UDPProxyServer plugin. The UDPProxyClient connects to UDPProxyCoordinator to get a list of servers running UDPProxyServer, and the coordinator will relay our forwarding request

## Member Function Documentation

virtual void RakNet::UDPProxyCoordinator::OnClosedConnection | ( | SystemAddress | systemAddress,
|  | RakNetGUID | rakNetGUID,
|  | PI2_LostConnectionReason | lostConnectionReason |
| ) |  |  | `[virtual]`

Called when a connection is dropped because the user called RakPeer::CloseConnection() for a particular system

Parameters:

  `[in]` | systemAddress | The system whose connection was closed
  `[in]` | rakNetGuid | The guid of the specified system
  `[in]` | lostConnectionReason | How the connection was closed: manually, connection lost, or notification of disconnection

Reimplemented from PluginInterface2.

virtual PluginReceiveResult RakNet::UDPProxyCoordinator::OnReceive | ( | Packet * | packet | ) | `[virtual]`

OnReceive is called for every packet.

Parameters:

  `[in]` | packet | the packet that is being returned to the user

Returns:
  True to allow the game and other plugins to get this message, false to absorb it

Reimplemented from PluginInterface2.

void RakNet::UDPProxyCoordinator::SetRemoteLoginPassword | ( | RakNet::RakString | password | ) |

For UDPProxyServers logging in remotely, they must pass a password to UDPProxyServer::LoginToCoordinator(). It must match the password set here. If no password is set, they cannot login remotely. By default, no password is set
