Re: NAT444 or ?

In a typical DS-Lite deployment you won't be using NAT444. One of the key advantages of DS-Lite (and A+P, I believe) is that there's only one level of NAT between the end user and the public internet.

yep. and in ds-lite that nat is in the core, so you talk to comcast's lawyers when you need a new alg. with a+p, the nat is under customer control, and they just go to best buy to get the cpe that supports the alg that they want. randy
