    Merhaba arkadaşlar,
    Benim elimde 2501 router var. serial 0 ve Ethernet bacağına bağlı adsl modem load balance çalışıyor. Sorunum ise: serial 0 down olduğunda direkt bütün trafik adsl modem e yönleniyor, ancak adsl modem down olduğunda yine load balance yapmaya çalışıyor.Adsl modem down olduğu halde ona paket göndermeye çalışıyor. Bu yüzden internete olan trafiğimizin yarısı kaybolmuş oluyor.bu sorunu nasıl aşabiliriz?
