well i am getting the following error:
6 Jan 20 2011 11:51:54 106015 192.168.26.18 60966 192.168.127.1 2404 Deny TCP (no connection) from 192.168.26.18/60966 to 192.168.127.1/2404 flags RST on interface JA_INSIDE
192.168.26.18 is connected to the router on 10.20.33.2.
192.168.127.1 is electrical RTU's connected remotely to my outside interface of the firewall. Some IP's of 192.168.127 range connecting with success however some not. For the unseccessful ones the get ther deny tcp error. please help.
We cannot say much just with the 106015 Deny tcp no conn message. All that says is that the firewall did not have a conn in the table to allow that packet through (in your case it was a reset packet). Pls. look at the built and teardown messages for the same connection so you can get more information.
