Esforçando-se para obter acesso remoto do MS SQL ao trabalho

Question

Ainda estou tentando obter um acesso remoto ao MS SQL Server em uma das minhas máquinas Windows.

Eu permiti o acesso no meu firewall do Windows como pode ser visto aqui e aqui . Eu também abri o porto no CoMoDo FW como pode ser visto aqui .

Mas tentar acessar a máquina pelo Linux com busybox telnet 192.168.1.4 1433 não produz "Connected".

O próprio servidor está configurado para aceitar as conexões remotas.

Que outras configurações estão faltando?

Obrigado.

  Adds firewall allowed program configuration.

  Parameters:

      SUBNET - Allow only local network (subnet) traffic through firewall.
      CUSTOM - Allow only specified traffic through firewall.

  addresses - Custom scope addresses (optional).
              This comma-separated scope can contain IPv4 addresses,
              IPv6 addresses, subnets, ranges, or the keyword LocalSubnet.

  profile - Configuration profile (optional).
      CURRENT  - Applies to the active profile.  Active profile can be domain,

      add allowedprogram program=C:\MyApp\MyApp.exe name="My Application"
          mode=DISABLE
      add allowedprogram program=C:\MyApp\MyApp.exe name="My Application"
          mode=ENABLE scope=CUSTOM addresses=157.60.0.1,

      IMPORTANT: "netsh firewall" is deprecated;
      use "netsh advfirewall firewall" instead.
      For more information on using "netsh advfirewall firewall" commands
