ALL,
Eu costumava ser um usuário feliz do ZoneAlarm. No entanto, recentemente eu precisei abrir uma porta em uma das minhas máquinas (Windows 8.1, porta 1433 para SQL Server) e descobri que esta é aparentemente uma tarefa impossível. Então, eu perguntei e foi dito para usar o CoMoDo.
Eu baixei e instalei, mas agora parece que ainda não consigo acessar remotamente o servidor. Tanto o CoMoDo quanto o Windows FW estão ativos e achei que abri a porta em questão em ambos. No entanto, tentar telnet para a máquina para a porta 1433 resulta em "Tempo limite da conexão esgotado".
E então, minha pergunta é: como abrir uma porta corretamente no Windows 8.1 FW e no CoMoDo FW?
Eu também devo acrescentar que isso é para minha LAN local em casa.
Obrigado.

Aqui está a saída de algumas etapas da solução de problemas que fiz após o acompanhamento da resposta que recebi.
