memfilesizelimit

Set the maximum file size (in megabytes)

The maximum file size allowed is 10% of the

 

 

 

FortiGate RAM size. For example, a

 

 

 

FortiGate unit with 256 MB of RAM could

 

 

 

have a threshold range of 1 MB to 25 MB.

 

 

 

Note: For email scanning, the oversize

 

 

 

threshold refers to the final size of the email

 

 

 

after encoding by the email client, including

 

 

 

attachments. Email clients may use a variety

 

 

 

of encoding types and some encoding types

 

 

 

translate into larger file sizes than the

 

 

 

original attachment. The most common

 

 

 

encoding, base64, translates 3 bytes of

 

 

 

binary data into 4 bytes of base64 data. So a

 

 

 

file may be blocked or logged as oversized

 

 

 

even if the attachment is several megabytes

 

 

 

less than the configured oversize threshold.

How file size limits work

The memfilesizelimit is applied first to all incoming files, compressed or uncompressed. If the file is larger than the limit the file is passed or blocked according to the user configuration in the firewall profile.

The uncompsizelimit applies to the uncompressed size of the file. If other files are included within the file, the uncompressed size of each one is checked against the uncompsizelimit value. If any one of the uncompressed files is larger than the limit, the file is passed without scanning, but the total size of all uncompressed files within the original file can be greater than the uncompsizelimit.
