TCP packets passes from Access List but drops due to TCP reset
Posted on 2008-10-14
I have a challenging Issue here, We have a source trying to connect to the Server in the inside network.
Source: 10.11.5.173 ( WYSE TERMINAL), Destination : 10.10.10.170
As source has problem in connecting to the server, i ran the Firewall debugs and collected the following debugs, the same source conencts to another server on the same network fine, and that pretty much rules out the issue with the Firewall Blocking the connection over all, But i want to get tehse following debug meesageges deciphered so that i can get an indication whether it is caused by the Server inside the network and not the Firewall.
