Dear friends,

I got these logs in my pix 515E,

Sep 20 17:01:46 10.1.1.1 local6:info Sep 20 2006 17:01:14 fw01 : %PIX-6-302013: Built outbound TCP connection 208673 for Outside:172.16.1.1/23 (172.16.1.1/23) to Inside:172.30.1.2/1319 (172.30.1.2/1319)
Sep 20 17:01:47 10.1.1.1 local6:info Sep 20 2006 17:01:14 fw01 : %PIX-6-302014: Teardown TCP connection 208673 for Outside:172.16.1.1/23 to Inside:172.30.1.2/1319 duration 0:00:00 bytes 0 TCP Reset-O

The pix heared 'Reset' request from its interface Outside as I know, but who sent this request? is it nat related?

Could you help me? thanks!

This has got me intreged. Not been able to find out much about this so i will ask one of our distributors technical people what this does in fact mean. I have read somewhere that it doesn't necessarily mean anything its just that the logging hasn't kept up; what ever that means :)

Will try and find out for ya

Apparently the TCP Reset-I means that the connection was reset from the client on the Inside and the Reset-O means that the connection was reset from a client on the outside.

Cheers
