UDP Payload replace destination IP with iRules

Yes of course, So, we have a data group called NATNET that includes networks: 10.12.0.0/24 10.12.1.0/24 10.12.2.0/24 10.12.44.0/24 10.12.60.0/24 Example Scenario: There is an incoming packet to our forwarding virtual server with Source IP : X.X.X.X and Destination IP : 10.20.30.12 When the packet have the destination ip that matches in the networks contained in the data group NATNET ( i can check it by using an IF condition with a scan fuction and compare it) But now inside the IF condition (So, the condition is true ) i want to Translate the destination ip like a snat irule like this: scan [IP::local_addr] "%d.%d.%d.%d" a b c d now i want to translate the Destination IP in --> 192.12.$c.$d i Hope i was clear enough to understand Thanks in advance for all your support
