Aydin selam,

ping packetlerini 32 byte in üzerine çikarip denedin mi. Zannediyorum giden gelen packet ler büyük ise bu sorunu yasiyorsun. Merkez ATM, kenar uç g.shdsl de ayni soruna yakin ben de rastlamistim. Sorun, Türk Telekom Izmir bölgenin g.shdsl ucu ATM e tanimladiklari configuration üzerine uygulanmis policy lerden kaynaklaniyordu. tanim üzerindeki policy leri kaldirdiklari zaman eminim düzelecek.

Kolay gelsin.

  Merhabalar;
  Merkezde bulunan 155 Mbps.lik ATM STM - 1 uzerine bir uc noktamizdan G.SHDSL noktadan noktaya   baglanti yaptik hersey duzgun gozukuyor. Ping atiliyor, nslookup yapiliyor hatta rdp bile yapilabiliyor   ancak http ile baglanilamiyor. Merkez ve uc nokta ayarlari asagidaki gibi :

  Not : Telekom sorun olmadigini soyledi hatlarda ve tanimlamalarda ayrica ara sira debug atm 0 dedigimde   su hatayida aliyorum : Mar 1 03:16:14.511: ATM0: AAL5 rx errors (status = 2C030000) boyle devam ediyor...
