Hi RoyMalik,Can you try this?when CLIENT_ACCEPTED {
	set lastOctet [getfield [IP::client_addr] "." 4]
	if {[expr $lastOctet % 2] == 0} {
		log local0. "$lastOctet is even"
		node 10.10.70.100
	} else {
		log local0. "$lastOctet is odd"
		node 10.10.70.101
	}
}or you can use this iRule.when HTTP_REQUEST {
	switch -glob [IP::client_addr] {
		"*1" -
		"*3" -
		"*5" -
		"*7" -
		"*9" { node "nodeName_10.10.70.101" }
		default { node "nodeName_10.10.70.100" }
	}
}
