Connection timeout while uploading via http - 26.Feb.2007 12:13:50 PM

Hello All,

I have a problem with uploading a file via the webproxy client, mostly with large files to an .net upload feature on a specific webserver. The error is:

Error Code 10060: Connection timeout
Source: Firewall

When switched to the secure-nat client the upload goes well most of the time (better as with proxy configured). Not always, sometime's I see the 10060 error also with the secure-nat client. I think the connection to the webserver is the problem, in the traces I have made I see tcp errors. Uploads to another website with the same type of upload method goes well.

Is there another re-try-count or time-out value when the traffic is passed through the Web Proxy Filter/ or when the webproxyclient is used ( is the secure-nat http traffic also passed through tis filter?) and is this configurable?

I am using as proxy: Windows 2003 + SP1, ISA2004 Ent. SP2 ( 2 member)

thanks in advance.

Problem solved!

There was a misconfiguration between the isa-server and a checkpoint firewall.
The solution was to change the parameter EnablePMTUDiscovery from 0 to 1.
