WAN Travando.



  • Boa tarde, amigos!

    Estou com um problema no pfSense de uma filial da empresa que trabalho.
    Inicialmente a placa de rede WAN estava travando constantemente, troquei a placa e o problema parecia ter resolvido. Porém, ela voltou a travar, percebi que antes de travar gerou o seguinte log:

    Alguém tem ideia do que pode ser?



  • Se vc já fez a troca da placa e mesmo assim persiste, tentar mudar a placa de rede de slot.
