I have a PIX 525 and sometimes our outside customers can´t connect with a internal server
In the log I see the following:
%PIX-6-302013: Built inbound TCP connection 118247 for outside:172.16.9.167/1992 (172.16.9.167/1992) to dmz:10.9.82.5/3389 (172.16.8.40/3389)
%PIX-6-302014: Teardown TCP connection 118247 for outside:172.16.9.167/1992 to dmz:10.9.82.5/3389 duration 0:00:01 bytes 11 TCP Reset-I
It looks like the internal server is sending a tcp reset after one second conection, but I don´t know why?
I checked the internal server configuration, and the amount of conections to the server, but everything is OK.
