[FW1] packet drop on port 1097/1074



Title: packet drop on port 1097/1074

Dear all,

I saw a lot of dropping (TCP by rule 0; reason: unknown established TCP packet) in my log since yesterday--all send by one of my mail servers to the rest of my FWs.  Also, it uses the same s_port: 1097/1074.  Since my mail server works fine (no particular activity going on as before), I wonder if this is some kind of illegal activities to my network.  Could someone give me some ideas about this?  I really appreciate any help.  Thanks in advance.

Best Regards,
Chi-lien Lee
