Any ideas for an "isp" in gns3??

in CCNA & CCENT
Hi, I have configured 2 different site networks in gns3 with vlans etc... Both sites connect through a serial link but i also want to create an "isp" or "internet" cloud where the user's on 2 sites can ping out to an Internet address such as 8.8.8.8 and have it reply! What is the best way to do this?? Would a router with a cloud symbol be my best bet with a loopback interface of 8.8.8.8?? Need some help and advice here.
