I am renting a wireless router with cable connection from my local ISP.

I want to setup my Buffalo 300nh router with dd-wrt before returning the ISP's wireless router.

Is this possible for me to do? i.e. can I connect directly to the 300nh, wipeout the existing firmware with dd-wrt and make sure everything is working before returning the ISP's router?

Is it possible to test it live by connecting a cable from the ISP router to the 300nh for internet connectivity?

Yep, totally. If your router has the login credentials for your ISP, then you won't be able to test that without unplugging the ISP router, but everything else should be testable.
