Olá amigo!
Você tem que ter 3 placas de rede na maquina !
Se for ADSL de operadoras diferentes utilize DNS publico !
Ex: primario 208.67.222.222
secundario 208.67.220.220
estes DNS funcionam com quase todas operadoras .
Colocar os modems em modo router !
Dois ADSL
1024k 10.112.0.0 e 512k 10.111.0.0
