IRule to redirect to another side based on network

All,

 

 

I am trying to write an Irule to redirect users who are not on our local site to another page. I have written this Irule but I am unsure if the Irule can accept subnets.

 

 

when HTTP_REQUEST {

 

if { [[IP::client_addr] is "10.1.0.0/16"] } {

 

pool http-pool

 

} elseif {

 

[[IP::client_addr] is "10.2.0.0/16"] } {

 

pool http-pool

 

} elseif {

 

[[IP::client_addr] is "172.16.0.0/16"] } {

 

pool http-pool

 

} else {

 

HTTP::redirect "http://192.168.0.12/local_only.jsp"

 

}

 

}

 

 

Basically anyone who connects with 10.1.x.x or 10.2.x.x or 172.16.x.x should get the site, but if you connect from 10.3.x.x you get redirected.

 

 

Thanks

    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.
