Which OS is running on the PC?

What is the version/model of the firewall?

Check if this document helps you?

I just had this capture message happen to me.  mss 1380,nop,nop.   The resolution was that the source address ip address was incorrect.  I performed a nslookup of the name and the ip address was wrong.   I change it on the ASA firewall by doing a  object group name then put host ip address.    which on the new 9.x version it will change it to all the down stream statements.   it was sweet.   I asked my client to try it again and they were able to connect with no problem.    hopefully this will help someone else looking for the resolution.
