Failing to get to outside webpage - Session being reset

Hello guys,

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:201.116.168.172/6666 to inside:172.16.x.x/3586 (65.204.x.x/52001)

Teardown TCP connection 726440542 for outside:201.116.168.172/6666 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.

Jennifer,

Thank you for offering to assist.

I really appreciate that!

We have determined that Websense is blocking the site & were able to figure it out by disabling websense for a minute.
