Bom dia pessoal,
tenho 2 servidores FreeBSD com carp pronto e funcionando. Porem o carp não
está funcionando 100% com o mpd5.
Para tentar resolver esta pendencia, abandonei o carp neste momento, ou
seja, o mpd esta listen no IP físico do servidor.
Eu estou utilizando Mikrotiks como clientes deste MPD e o problema é que  a
conexão fica caindo com mt frequencia:
