Item Description
Filename
Specify filename keywords for the filename filtering entry.
You can specify up to 16 filename keywords separated by commas.
• If you specify a filename keyword in the format of filename.extension, the
firewall will perform exact match for this keyword. You can use a wildcard (*)
to stand for the filename part, the extension, or a string of up to 6 characters in
the filename or extension. In each keyword, wildcard * can be present only
once in the filename and once in the extension. If multiple dots (.) are present
in the keyword, the content following the last dot is regarded as the extension.
• If you specify a filename keyword containing no dots, the firewall will perform
fuzzy match for this keyword. You can use wildcard * to stand for a string of up
to 6 characters in the keyword. In each keyword, wildcard * can be present
only once.
Protocol
Specify the protocol for which the filename filtering entry is configured. The
protocol can be SMTP, POP3, or FTP.
• SMTP filename filtering entries are for attachment name filtering in SMTP
filtering policies.
• POP3 filename filtering entries are for attachment name filtering in POP3
filtering policies.
• FTP filename filtering entries are for upload filename filtering and download
filename filtering in FTP filtering policies.
