File download issue through ASA

saifuddin.miyaji · ‎12-13-2011

Hi,

We have ASA 5540 with 8.2 SW. We are trying to download a file (3 MB pdf) from https session which fails if done behind the firewall. In case, the client bypasses firewall, the file gets downloaded as usuall. Interesting thing here to note is that when client is behind the firewall, its takes a long time to download the file and the file size always 312 Bytes, of course its a corrupt file.

We have chaged the MSS setting but did not help.

Did anybody face such problem before?

Thanks

Saif

Julio,

We are collecting logs on syslog server but the amount of logs is large that its extremely difficult to trace this particular session from syslog.

Hello,

I would like too see the logs at the time you are facing the issue, when the download its slow.

Is it possible that you could provide your ASA configuration,

Are you using a CSC-SSM or AIP-SSM?

Regards,

Julio.
