A PIX-515 running v7.2(1) is continuously dropping packets because of exceeding the embryonic counter limit which is currently set to 500.
The sessions dropped are connection requests initiated from outside to internal clients which are prohibited by the ruleset (ACL). Why is the PIX dropping connection requests with the "embryonic session limit" feature and not with the ACL deny statement ? Unfortunately the PIX is also dropping legitimate TCP connections. What could be the reason for that and is there a way to influence this misbehaviour ?
we have also this problem with PIX 7.2.3 from Outside to a DMZ Interface with a mailsystem as destination. I get the syslog: >%PIX-6-201010: Embryonic connection limit exceeded 100/100 for inbound packet from xxx.xxx.xxx.xxx/1049 to xxx.xxx.xxx.xxx/25 on interface outside
So i have only the limit of embryonic connections in a static command not in a policy-map with a set connection statement.
I've tried to remove the static command, clear the xlates and set it new, no change is visible: I get still this syslog messages. please can anybody help?
