Fala galera! Estou com um probleminha para instalar dois servidores PPP, que
vao se conectar atraves de uma LP de voz da Telemar.
Seguem abaixo, as configuracoes do PPP nos servidores 1 e 2. Nao consigo
pingar a maquina da outra ponta da LP, somente a maquina local. Todos os
sinais do modem estao ativos, sinalizando que o meio fisico, os cabos e os
modems estao OK. Quando pingo a maquina da outra ponta, o LED de Tx do modem
pisca normalmente, a cada pacote enviado.
Alguem sabe dizer se esta faltando alguma configuracao?
obs: Liberei tudo no ipchains.
Configuracoes do Servidor 1:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
