This isn't a very good idea. Google uses a very short TTL on its www.google.com A records (136 seconds). So they are subject to change every 136 seconds. As we have pointed out to you before, DNS names are translated into a list of IP addresses when the firewall is started or restarted. So any changes in the set of addresses associated with the DNS name are not going to be reflected in the active ruleset. If you still think you want to try this, see http://www.shorewall.net/configuration_file_basics#dnsnames.
