PIX Problem - users getting blocked to outside interface

[sgendron9]

I have a pix 515e...and I am somewhat of a newbie. Every once in a while (seems like more lately) workstations are not able to access the outside interface. This seems to happen randomly and I can not figure out a pattern. I get the following in the syslog when the problem occurs:

%PIX-6-302014: Teardown TCP connection 49145 for outside:AAA.BBB.CCC.DDD/9100 to inside:192.168.1.41/1757 duration 0:02:01 bytes 0 SYN Timeout

If I change the IP of the workstation the problem seems to be resolved....but this is only a temporary solution.

The running config is attached. Any help is appreciated...again I'm somewhat of a newbie.

The SYN Timeout you are receiving from the PIX means that the PIX forced the termination after 2 minutes of waiting for three-way handshake completion.

Do you know what would cause this to happen ? When it happens workstations cannot access the outside interface at all. Changing the inside IP resolves the issue temporarily.
