Mutiple Email Server with static Addresses

Hi Damien,

You could defined one datagroup (called a class in the bigip.conf) for each pool of a type 'address' where you define the valid client IP addresses which should use that pool. You could then check the client IP address against the datagroups.

You would define the datagroup outside the rule (under Local Traffic >> iRules >> Datagroup tab). The definition in the bigip.conf would look like this:

 
 class mail_10.0.0.1_clients { 
    network 192.168.1.0/24 
    host 192.168.20.1 
 } 
 

 
 class mail_10.20.0.1_clients { 
    network 192.168.2.0/24 
    host 192.168.40.1 
 } 
 

The rule would look like this:

 
 when CLIENT_ACCEPTED { 
  
     Check if client is part of the first datagroup 
    if {[matchclass [IP::client_addr] equals $::mail_10.0.0.1_clients]}{ 
  
        Client matched first datagroup so use the corresponding pool 
       pool mail_10.0.0.1_pool 
  
    } elseif {[matchclass [IP::client_addr] equals $::mail_10.20.0.1_clients]}{ 
  
        Client matched second datagroup so use the corresponding pool 
       pool mail_10.20.0.1_pool 
  
    } else { 
  
        Take some default action? 
       pool default_pool 
    } 
 }
