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.
