trying to piggy back airport extreme

[ebaydan777]

i got AT&T U-verse internet today and it came with a modem/router with the installation

the thing is id love to connect my airport extreme to my mac computers because theyre all running on a/b/g/n....how would i go about doing this??

i see 4 lan connections on the back and a BROADBAND connection as well...would i just drop this broadband connection to my airport extreme router and be good?

I'm also curious if anyone is using ap extreme with u-verse. They're installing uverse this sun for me!
