I try to send large data zip files over a 2Mb Point to Point Lease Line(Fiber Link). when trying to upload 1.6GB one single zip file over this line, i got error, Connection reset by Peer. I use WS FTP LE, even i tried using DOS based FTP.EXE
also but same error.The error occurs only with large files,i can send and receive small files(100MB or 200MB or 300MB) without any problem,
SERVER Using IIS FTP(NT Option Pack 4.0)/Tried on Win 2K IIS FTP. CLIENT tried on WSFTP,Dos based FTP.exe,Cuteftp
Scenario: FTP Server--->Cicso 2610 Router ---->Cisco Router---->FTP Server
No firewalls, No ACLs nothing, simple routing.
Tried on: 1.Using both PASSive Mode and Active Mode,
2.Sending data on Binary format,
3.no routing problems(can send smaller size data files).
4.Tried on Differnet Server, Lease Line is ok.
5. Router to Router ping rate success:100/100
6. FTP Server to FTP ping rate success:(100%)
7. tried on changing MTU size,
i) MTU size changed to 1600 on both routers,and
ii)using MTU size 1500 on all devices.
Observation: When i send the 1.6GB ZIp file ping rate between ftp to ftp is intermittent ie. 4 or 6 replys 1 or 2 timeout,8 or 10 replys 2 or 3 timeout, then at 700 or 800MB FTP error, Connection Reset by peer. smaller size files no problem.
If you want i can provide more details.
Appreciate your kind help and sugessions.
