I have AT&T u-verse small business connection at my office with a =20
static IP setup, and my experience matches with the AT&T tech said. =20
We have a separate router behind the AT&T router. The AT&T router is =20
an Arris (former Motorola) NVG595. Our router has a static IP out of =20
our subnet and does NAT for the office network.
As far as I can tell, the u-verse supplied router cannot be replaced =20
with something less sucky. The problem is getting the 802.1x =20
certificate needed to authenticate on the wan port.
I dislike AT&T's hardware as it has more limitations than just this, =20
but some of those limitations can be worked around with an additional =20
router downstream of it.
