ASA Clientless SSL Tunnel - File Uploading

Unanswered Question
Apr 9th, 2010

What governs the limit of file size that can be uploaded to a network via ASA clientless web vpn upload function?

Testing it I see it works fine with small files.  But I was trying to upload a large file - 12GB and the screen just

seemed to go blank and I did not see traffic at the local router to indicate that traffic was going via the tunnel.

Thank-you.

What code are you runing?

There might be a 2 G limitation.

Try "show run all group-policy DfltGrpPolicy | i upload".

I'm running 8.2.x, upgrading to 8.3.x tonight.  I'll try out that command before and after.  Thanks.

Please make sure you have also upgraded the memory prior to upgrading to ASA 8.3, and check out all the new feature before you upgrade it (NAT is completely different on version 8.3, and all the previous version of ASA, and also global ACL). There is also bug with migrating/upgrading to 8.3 as some config is not upgraded correctly.


Here is the release notes for 8.3 for your reference:
