source based pool selection (irule not working)

 

Hello all , i am trying to creat an irule for source address based pool selection but irule is not working.

 

 

 

please check the syntex

 

 

---------------------------------------------

 

 

when CLIENT_ACCEPTED {

 

if { [IP::addr [IP::client_addr] equals 10.113.0.0/16] } {

 

pool Outbound-Voice-Video

 

} elseif { [IP::addr [IP::client_addr] equals 203.128.0.0/24] } {

 

pool Outbound-Public-Servers

 

} elseif { [IP::addr [IP::client_addr] equals 203.128.1.0/24] } {

 

pool Outbound-Public-Servers

 

} elseif { [IP::addr [IP::client_addr] equals 203.128.4.226/24] } {

 

pool Outbound-Public-DMZ

    The syntax looks fine. You don't have a default case specified if the client IP doesn't match any of the rule conditions. Do you have a default pool configured on the VIP?

    What's not working? Can you add logging to the rule to verify the client IP the BIG-IP receives is what you're expecting?

    Here is an example:

    
when CLIENT_ACCEPTED {
   log local0. "Client: [IP::client_addr]"
   if {[IP::addr [client_addr] equals 192.168.99.0/24]}{
      log local0. "Matched: 192.168.99.0/24"
   } else {  
      log local0. "Didn't match: 192.168.99.0/24"
   }  
}

    Log output:

    : Client: 192.168.99.37

    : Matched 192.168.99.0/24
