I am seeing the above occur maybe once a day or once every other day, but
the source IP address is in an alias that is a list of aliases (and that
list contains my mail server aliases). Whenever I see this, I manually try
to telnet to the same IP on port 25 and the traffic is passed, yet the mail
server shows a failed connection attempt in the logs which coincides with
the firewall log as above. I have a rule that explicitly allows port tcp/25
as a destination from my inbound mail servers alias group, and then there is
a rule right beneath that rule that explicitly blocks outbound SMTP from all
IP addresses on the subnet, and I have logging turned on for that rule. So,
the rule beneath the one that should be triggered is being triggered
instead.
Is there a Bug/Race condition in rule evaluation??
No, those are RSTs and FINs coming after the state is closed, expected
behavior.
