- CLI Arguments mode: `java clientP2P.ClientP2P -- <clientTransportProtocol> <integratedServerHOSTNAME> <integratedServerPORT> <trackerHOSTNAME> <trackerPORT>` (default tracker port 6969 (range 7000 -> 7999) and server port: server 7070 (range 7000->7070))
- CLI Arguments mode when using with a nat: `java clientP2P.ClientP2P -- <clientTransportProtocol> <integratedServerHOSTNAME> <integratedServerPORT> <trackerHOSTNAME> <trackerPORT> <serverBindingHOSTNAME> <serverBindingPORT>` (default tracker port 6969 (range 7000 -> 7999) and server port: server 7070 (range 7000->7070))
