Hi,

Connection is being torn down because one of the ends is setting FIN flag on the TCP packet. This is not, however, an issue w/ the firewall.

You may run some traffic captures in order to determine which end is sending the FIN packet. Here's a good link for captures example:

Hi juarez,

Thanks for your reply. Do you know by any chance what can cause on of the ends to send a FIN flag in the packet. Are there some reasons to that?

Thanks

Greg
