Policy Exclusions
Each policy contains the list of exclusions that specifies which domain names, IP addresses and URLs should never be filtered in this policy. It is possible to add exclusions based on (partial) domain name of the remote server, its IP address, IP address range or IP subnet. Specific URL matching Perl style regular expression can also be excluded from filtering.
Please note that for domain name exclusions wildcards are not supported. Do not use ? and * in exclusion domain names.
