TCP out of order / TCP Retransmission / TCP Previous segment lost
I have a strange issue, am connected to the internet and can access any websites except few (does not give page can not be displayed and it does not give anything its just waiting all the time for respond), am sure its not the website problem as i could open the same website from a different location.
so i decided to capture the packet and look whats wrong while accessing those few websites and what i could see is a sucessfull TCP handshake followed by my http request and the problem starts, TCO out of order and TCP retransmission and TCP previous segment lost..

Federico - did you ever solve your issue? I saw a couple threads that you started similar to my issue.... and this one.
Windows machine, connecting to an HTTPS site with either Firefox or IE. Page is rendered with no problems, but downloads from the site fail at ~0-300Kb.
Download is successful when connected directly to the edge router, bypassing the ASA
Download is successful from other ISP's.
And the weird part - Download is successful on a Max OSX computer running Firefox - behind the asa..
It seems to be a combination of the ASA and Windows.
Wireshark of the two downloads is remarkably similar - both have TCP out of order, Dup Ack... the only real difference is the failed download has a couple WindowFull/ZeroWindow/WindowUpdate combinations.
