## Basic Information

**Point-to-Point Tunneling Protocol (PPTP)** è un metodo ampiamente utilizzato per **accesso remoto** a dispositivi mobili. Utilizza **la porta TCP 1723** per lo scambio di chiavi, mentre **il protocollo IP 47** (Generic Routing Encapsulation, o **GRE**), viene utilizzato per crittografare i dati trasmessi tra i peer. Questa configurazione è cruciale per stabilire un canale di comunicazione sicuro su Internet, garantendo che i dati scambiati rimangano riservati e protetti da accessi non autorizzati.

**Default Port**:1723

## Enumeration
```bash
nmap –Pn -sSV -p1723 <IP>
```
