File Upload behind a firewall

Hi,
I have a form on my website which contains a file upload field and works no problem. However, one particular user had a problem uploading a file through the form. After further investigation, we came to the conclusion that it was due to the user being behind a firewall. Is there a way around this or is it just something that we will have to deal with?
Thanks.

I have never experienced anything like this myself before. What kind of firewall is (s)he using? A hardware firewall or a software firewall?

You can test the same pc out of the regular network using a wireless card?... if the user can upload the file most likely is a firewall issue, then you must check the defined rules in the FW and modify/setup it accordingly.

Surely a firewall would not be the issue seeing as the file is being uploaded over HTTP and the user would not even see the site if that was blocked?

Yeah, it sounds a bit absurd...

It's possible you made a mistake. How did you come to that conclusion?

well... that depend of the kind of firewall that you have and how you control the traffic with it... in some FW you can control any kind of traffic including http... in my case I can control the size of download/upload files either using http or ftp... maybe could be a similar situation for the specific user? ... doesn't sound too absurd to me... but then again... I can be wrong
