Na minha caixa Ubuntu eu estou executando o software de licenciamento flexlm na porta 27000 e eu sou capaz de puxar a licença da porta para executar o software de simulação localmente.
Eu também estou tentando executar o mesmo software em outra máquina Linux (opensuse) usando a licença flexlm da caixa Ubuntu. No entanto, minha caixa opensuse é incapaz de se comunicar com a porta 27000 na minha caixa Ubuntu.
Eu desliguei o firewall na caixa do Ubuntu, brinquei com o iptables e quando eu faço um nmap da minha caixa opensuse para o Ubuntu, a mensagem que recebo é que a porta 27000 está no status filtrado. Meu entendimento é que o status filtrado não permite que a caixa opensuse se comunique com o Ubuntu.
Minha pergunta é como alterar a porta 27000 do status filtrado para o status aberto? Espero que alguém possa me ajudar. Obrigado.
Andy aqui é o iptables e estou usando o UFW
