## Informações Básicas

**Point-to-Point Tunneling Protocol (PPTP)** é um método amplamente utilizado para **acesso remoto** a dispositivos móveis. Ele utiliza **TCP porta 1723** para a troca de chaves, enquanto o **protocolo IP 47** (Generic Routing Encapsulation, ou **GRE**), é usado para criptografar os dados que são transmitidos entre pares. Essa configuração é crucial para estabelecer um canal de comunicação seguro pela internet, garantindo que os dados trocados permaneçam confidenciais e protegidos contra acesso não autorizado.

**Porta Padrão**:1723

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