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.
