Unable to Upload a Large File

When encountering this problem, we have found that the issue could be a setting on your Firewall, which limits large uploads into your network. To correct this, check the Firewall settings and ensure that there is not a limitation on the size of files being transmitted across the Firewall into your network? Some of the settings that you may want to look for would be "tcp-mss-sender" for outbound traffic and "tcp-mss-receiver" for inbound traffic. The values for those settings controls the maximum amount of data that can be sent in a single packet, and can sometimes be troublesome when transmitting large files.
