modem celular: desligamento do modem pppd

  • 772

Estou tentando estabelecer uma conexão de celular com a Verizon por meio do meu Multitech Multiconnect Dragonfly (MTQ-LVW3-B02). Consigo me conectar à rede da Verizon e obter um endereço IP. O problema é que depois de alguns segundos o modem desliga a conexão.

Tentei adicionar noipdefault ao arquivo de opções, mas também não funcionou.

Estou perdido e qualquer ajuda na depuração seria ótima.

    Eu descobri a resposta. O problema era que a Verizon cortaria uma conexão se recebesse 10 pacotes inválidos em um período de 2 minutos. O problema era que eu não estava fazendo o NAT dos pacotes corretamente, pois também o usava como roteador. Os pacotes enviados da LAN em ponte estavam sendo enviados para a Verizon com um IP de origem de 192.168.123.XXX. A Verizon (com razão) decidiu que esses pacotes eram inválidos e desligaria a conexão. A solução foi simplesmente adicionar esta regra do Iptables:

    iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE

  2. Não é uma resposta à sua pergunta, mas tive um problema semelhante com a AT&T e tropecei aqui procurando uma resposta.

    Descrição do meu problema

    Após 5-7 minutos, um modem celular com host Linux seria desconectado da rede. O Linux veria a ppp0interface desaparecer depois de pppdsair.

    Causa

    No meu caso, habilitei (sem saber) o DHCP para a ppp0interface por meio de um arquivo em /etc/systemd/network/ppp0.network. Pacotes DHCP com src=0.0.0.0 e dst=255.255.255.255 estavam saindo do modem celular, que a AT&T vê como tráfego inválido.

    Solução

    Eu apaguei o /etc/systemd/network/ppp0.networkarquivo (e a configuração DHCP). Isso impediu que o desapego acontecesse. Tudo relacionado ao pppd ainda funcionou normalmente ( ppp0obteve um endereço IP, sessões adequadas, etc).
