O que está causando a VPN continuar perdendo a conexão e, em seguida, se reconectando?

Todas as configurações da MTU são 1500. De onde vêm os problemas da MTU?

    

Answer 1

Você tem algum https (por exemplo, apache) no servidor? Porque isso pode causar queda de conexão se puder iniciar ... Tente outra porta e desative comp-lzo no servidor e no cliente também, porque é um pouco bugs.
