This check reports permitted IP protocol numbers. Specify the numbers of protocols that you want to examine in the name list. To specify a range, use a hyphen. For example, 100-255 specifies protocol numbers 100 through 255. Valid protocol numbers are 1-255. The file %SYSTEMROOT%\system32\drivers\etc\protocol maps protocol names to protocol numbers.
