Greetings.
I have a PIX 520 and my inbound users (who ftp data from us) keep
complaining about their connections getting timeout errors. I've turned on
debugging in the logs and I see a multitude of teardown events as such:
Mar 23 11:02:11 firewall Mar 23 2001 10:53:45: %PIX-6-302002: Teardown TCP
connection 491419 faddr x.x.x.x/45972 gaddr y.y.y.y/21 laddr z.z.z.z/21
duration 0:29:36 bytes 190361 (TCP Reset-O)
It's not JUST port 21, but since 99% of my inbound connections are for FTP
services from a select group of partners, this is by far the most prominent
example.
What causes this? How do I keep this from happening?
Thanks for your help,
Kevin
