Gostaria de configurar o encaminhamento de tcpporta 8000-> 192.168.1.16:4200no meu Mikrotik RouterOS.
Eu fiz o seguinte:
/ip firewall nat add dstnat chain=dstnat action=dst-nat to-addresses=192.168.1.16 to-ports=4200 protocol=tcp dst-address=<PUBLIC_IP> dst-port=8000
Quando tento usar o serviço da Internet, o seguinte comando simplesmente trava:
curl <PUBLIC_IP>:8000
Posso ver os contadores se movendo na regra NAT do Mikrotik (via WebBox).
Na máquina de destino, posso ver o seguinte em netstat -an | grep 4200:
tcp 0 0 0.0.0.0:4200 0.0.0.0:* LISTEN
tcp 0 0 192.168.1.16:4200 <REMOTE_HOST>:37720 SYN_RECV
Verifiquei que consigo me conectar à máquina localmente via curl 192.168.1.16:4200.
Não consigo descobrir o que pode estar errado :(
