Playing with an ASAv for the first time, infact first time ever with a ASA.

Is this possible to do via asdm:
Have a pool of IP addresses that a client Round Robins on. What I mean is that if Client makes a connection to cnn.com it looks he makes a connection from a pool of IP-addresses.
Sen in my FW log, that I sometime have visitors that visits my page that have 10.10.10.2,3,4,5,6 and so on, which look very cool. Hehe
