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.
