TCP Reset-I

am getting the follwong message in our PIX log: 2006-07-14 11:44:28 Local4.Info 192.168.12.9 %PIX-6-302014: Teardown TCP connection 52170120 for dmz1:192.168.*.*/64894 to inside:192.168.*.*/25 duration 0:00:00 bytes 0 TCP Reset-I. I know that the -I in the TCP Reset tells me that it is from the inside but inside what. This traffic is between the DMZ and inside interfacces, can I tell what direction the reset came from?

Re: TCP Reset-I

in this case,the reset is coming from the inside interface.I believe you have a smtp server on the inside interface and you are trying to access it from dmz.

please check the settings of server,if possible reboot it once,or open up a case with cisco TAC.

Re: TCP Reset-I

It means from the host on the inside interface i.e. from 192.168.*.*/25.

Is it an ESMTP mail server? Do you have "fixup protocol smtp"? If so "no ..." it.
