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.
