We have clients uploading documents (usually PDFs under 3MB in size) up to a web interface (using http only) on an internal web server. They clients are using the latest version of AnyConnect for windows and connecting to an ASA5510 running the latest 8.3 firmware. They are connecting from their home network over a cable or DSL connection.
I disabled Threat detection and can't see anything being blocked by the firewall. Everything else that our user are doing seems to be working flawlessly.
I ran a packet capture with wireshark and noticed a lot of packet loss. I have attached a screen shot.
Any advice would be greatly appreciated.
Solved! Go to Solution.
I fixed the speed/duplex and it seemed to make a huge difference. I should have known better, seems like a rookie mistake.
I also changed the MSS size just to be safe. Thanks a lot for the help!

Obscure things happen to the best of us, even if it is just duplex/speed settings somewhere in the path. That's what support forums like this are for -- bounce questions off other professionals and get peer help.
