Eu tenho a imagem Boot2Docker em execução em VirtualBox no meu mac. Eu uso o Kitematic para executar docker no meu Mac.
Eu tenho activemq docker em execução na porta 32769 in boot2docker vm. Eu tenho o aplicativo em execução que se conecta a activemq na porta 32769 .
Meu aplicativo aleatoriamente dá erro como abaixo.
[INFO] stompest.async.listener: Disconnected: Connection to the other side was lost in a non-clean fashion.

Para reproduzir isso, eu tenho que bloquear a porta 32769 e desbloquear novamente, então stompest tentará se conectar novamente e crie o mesmo erro.
Eu verifico ifconfig em boot2docker vm, mas cria aleatoriamente a porta.
Existe alguma maneira de bloquear a porta e desbloquear novamente?
