LABEL DESCRIPTION
Enable If this is a black list entry, select this option to have the ZyWALL apply
this entry when using the black list.
If this is a white list entry, select this option to have the ZyWALL apply
this entry when using the white list.
File Pattern For a black list entry, specify a pattern to identify the names of files that
the ZyWALL should log and delete.
For a white list entry, specify a pattern to identify the names of files that
the ZyWALL should not scan for viruses.
• Use up to 80 characters. Alphanumeric characters, underscores (
_
),
dashes (-), question marks (?) and asterisks (*) are allowed.
• A question mark (?) lets a single character in the file name vary. For
example, use “a?.zip” (without the quotation marks) to specify
aa.zip, ab.zip and so on.
• Wildcards (*) let multiple files match the pattern. For example, use
“*a.zip” (without the quotation marks) to specify any file that ends
with “a.zip”. A file named “testa.zip would match. There could be any
number (of any type) of characters in front of the “a.zip” at the end
and the file name would still match. A file named “test.zipa” for
example would not match.
• A * in the middle of a pattern has the ZyWALL check the beginning
and end of the file name and ignore the middle. For example, with
“abc*.zip”, any file starting with “abc” and ending in “.zip” matches,
no matter how many characters are in between.
• The whole file name has to match if you do not use a question mark
or asterisk.
• If you do not use a wildcard, the ZyWALL checks up to the first 80
characters of a file name.
