Occasionally, data is not properly downloaded from internet based sources, and rules cannot be generated with errors similar to:

php-fpm[]: /rc.filter_configure_sync: New alert found: There were error(s) loading the rules: /tmp/rules.debug:19: file "/etc/bogons" contains bad data - The line in question reads [19]: table <bogons> persist file "/etc/bogons" 
php-fpm[]: /rc.filter_configure_sync: New alert found: There were error(s) loading the rules: /tmp/rules.debug:202: syntax error - The line in question reads [X]: pass  in  quick  on $IPsec inet proto tcp  from $Network1 to $Network2 port $Ports tracker 123 flags S/SA keep state  label "USER_RULE" 

• If there are errors downloading the data, configurable attempts should be made to retry until successful data downloads or the number of attempts is exhausted. (with a configurable pause between attempts)
• If data is not in the expected format, for ports or cidr blocks, it should not be saved. (i.e. a 404/503 error text)
• If the rule points to an empty (or invalid) data file, it should not be loaded.
