RE: [FW1] Possible FTP timeouts from MS boxes

Hi there,

 

We also suffer from this problem. It seems to be the port that changed during transfers of the files. It all works well till suddenly the source port changes for some reason on the next file (which we found out by looking at the ftp server logs). Logged it with checkpoint by they say it's a Microsoft problem. This however did not happen with previous version of FW1.

Subject: [FW1] Possible FTP timeouts from MS boxes

All,

I am having an issue where I am FTPing a large number of small files from an NT to a Solaris box in the DMZ.  The firewall is allowing the data through but for some reason the connection gets closed prematurely ending the FTP before all the files are transferred. 

I had recently moved the solaris box from an old firewall (3.0b) to a new firewall (4.1).  The problem didnt appear until after the move.

To make matters worse, I have tested it on a few windows boxes and they all seem to have the same problem...and...I have tested it on a a few unix boxes and they work without a problem.

I have spoken with some people who mumble stuff about MS and the IP stack during FTP, but I have never heard anything about that. 

Has anyone seen this kind of problem before or anything like it?

Thanks
