I have an issue I am stumped on at the moment & thought you might be able to shed some light on.
I have an ASA 5520 for my firewall. (ver 8.0(4))
I have an external hyperlink that works from dsl at home but not from behind my corperate firewall.
When I filter my real-time log viewer for this destination address I see the build up and immediate teardown of the session.
The log indicates the teardown was initiated from inside.
The informational alerts are
Built outbound TCP connection 726440542 for outside:188.8.131.52/6666 to inside:172.16.x.x/3586 (65.204.x.x/52001)
Teardown TCP connection 726440542 for outside:184.108.40.206/6666 to inside:172.16.x.x/3586 duration 0:00:00 bytes 77 TCP Reset-I
Reset-I means that something (the firewall or my pc which is the source) is telling the firewall to end the session.
Anyone have an idea where I can look to figure out how to correct this?
The actual hyperlink I am using/ trying to get to leads to an address in Mexico but as I said I can access it from home.
Thank you in advance
