I have an ASA 5510 running 8.2(2) with all an outside, inside and dmz port. Have a server in the dmz running an uploading application. I have no problem uploading files from outside the network to the dmz server, but when uploading from the inside is when I have issues. I am able to upload a 250MB PSD file but the application fails when trying to upload a 100MB FLV file. Again, both these files will upload just fine from an outside connection and when sending from within the DMZ. We have tried other types of files and a smaller FLV with some success, but it seems that when I try to upload a compressed video file that is over say 30MB, the upload fails...again from the outside it works just fine with any file that I throw at it.
I have tried natting the traffic from inside to dmz and tried without nat. I have been on the phone with Cisco TAC and they have gone over my config and tell me that this should work. There are no errors on the ASA. We have have looked at the application and there are no errors either. This seems like the TCP connection gets interrupted.
Has anyone had any issues uploading files to a server in their DMZ from the Inside interface, but from any other connection it works fine? I know this is probably something simple and I am just over analyzing it, so any help will be greatly appreciated.
Thanks in advance.
