Benzeri başıma gelmişti. Windows paylaşım portlarını kapatan access-list yazıp, tüm arabirimlere uyguladığımda düzeldi sorun. MS paylaşımını kullanarak yayılan virüslerin saldırısı göçertmişti bizimkini çünkü.

  Selamlar,

  Loglarda memory veya diger tipte bir hata yok. NAT yapiyor ama fazla bir   adres cevrimi yok. Yaklasik 1Mbit civarinda bir trafik geciyor.

  Virus, p2p vs yok gozukuyor. CEF calisiyor. Access listleri kaldirdim ama   sonuc fazla degismedi.

  En fazla IP Input kullaniyor gozukuyor ama o da 2.4% bile gecmiyor toplam   ise %40'i gecmiyor.

  41 103532 16010 6466 2.12% 2.70% 2.35% 0 IP Input

  Yorumunuz var midir ?

  Kolay gelsin.

  Tesekkurler,
  Cumhur
