    You can try restructuring your iRule as follows to see if the error goes away:

    when CLIENT_ACCEPTED {

		snatpool snat_pool_A
	}	elseif { [IP::addr [IP::client_addr] equals 172.17.0.20] } {
		pool pool_B
		snatpool snat_pool_B
	}	elseif { [IP::addr [IP::client_addr]  equals 192.168.20.10] } {
		pool pool_C
		snatpool snat_pool_C
	}
}
