Question : Cutover from DSL to T1

My company is cutting over from a DSL connection to a T1.  The T1 has a standard RJ45 connection for our router.  We are using a SonicWall TZ 170 standard.  When I hook up the router to the T1 and go through the setup wizard on the SonicWall, it completes and the SonicWall reports that the WAN connection is up, however, I cannot browse the Internet.  I have checked and double checked the IP and DNS information and it is correct.  Is there something simple that I am missing?

I am marking this for 500 points since the T1 is already in place and I would like to cut over to it as soon as possible.

Thanks in advance.

Answer : Cutover from DSL to T1

I checked again with tech support for the T1.  The problem was on their side.  I am considering the question closed.

Thanks.
