A potential DNS Rebind attack has been detected [RESOLVIDO]
« on: September 03, 2019, 01:56:11 am »
Olá pessoal.

Criei um NAT de encaminhamento de porta para um servidor interno, para acessar a porta 80. O acesso é através de uma endereço DNS exemplo.teste.com.br.
Quando acesso fora da minha rede local funcionar perfeitamente, porém quando acesso o mesmo endereço a seguinte mensagem é exibida:
A potential DNS Rebind attack has been detected.
Try to access the router by IP address instead of by hostname.

Tentei inúmeras configurações do NAT e também procurei algumas soluções no google, nenhuma funcionou. Alguém pode me ajudar?

Resolvi fazendo a seguinte configuração:

Firewall -> Settings -> Advanced
Enable:
- Reflection for port forwarding
- 1: 1 reflection
- Automatic outbound NAT for reflection NAT

Firewall -> NAT -> Port Forwarding
WAN    TCP    *    *    WAN address    80 (HTTP)    192.168.1.50    80 (HTTP)    Name

Olá

Consegui resolver esse problema adicionando a seguinte informação em:

System / Settings / Administration
 - Alternate Hostname: my.host.on.ddns.service
