IRule to redirect to another side based on network

You can set up your hosts and networks in a class (datagroup in the GUI) and then reference that class in a rule. Here is an example:

class my_hosts_networks_class  {
   network 10.0.0.0 mask 255.0.0.0
   host 192.168.0.100
}

rule filter_clients_rule {
   when HTTP_REQUEST {
      if { [matchclass [IP::remote_addr] equals $::my_hosts_networks_class] } {
         pool http-pool
      }
      else {
         HTTP::redirect "http://192.168.0.12/local_only.jsp"
      }
   }
}

You can either add the class in the GUI under iRules >> Datagroups, or edit the bigip.conf and run 'b load' to initialize the change.
