I have a problem I am configuring a Cisco pix 515e, I have two VPN tunnel site to site Working and the firewall up and running, but I have a problem with the firewall when I tried to download files from certain sites I can't, for example I can't download files from Mozilla http://www.mozilla.org/download.htm or www.microsoft.com among many others.
I can download files from torrents, and most ftp servers, as well update my computers from Microsoft widows update.
For example if I download internet explorer 8 from Microsoft site, the download starts but only download a few Kb, other times the download doesn't start.
I also have problems with you tube, the problem is the following, if I tried to see any video the clip is very slow to start, and in some cases I can't see the clips.
I attach the log file from Cisco pix to help troubleshoot the problem, as well a configuration file.
