Ola gente, estou tentando diagnosticar o pq de um equipamento não consegue comunicar. Um equipamento com IP x.x.x.x tenta se conectar ao IP x.x.x.x:5001. Mas não consegue.

Detalhe, quando tento por telnet da certo. Mas quando o equipamento que é a central de alarmes não funciona. Segundo a pessoa que esta no local. O Equipamento não retorna conexão ok, mas podemos ver os pacotes de retorno. Podem me dar uma dica?
