No link on SonicWall 3060 Interface When Connected to Cisco 2821 Router

Need to connect a Cisco 2821 Router to my Sonicwall Pro 3060.  I have enabled the interface X4 as a DMZ, assigned a static IP, however when connected to the Cisco Interface, No link is shown.  When powering on the Cisco, the link comes up briefly, but then shuts down.

I plugged in the Sonicwall X4 interface to a switch, and I get a link.  I plugged in the Cisco GE 0/1 interface to a switch and get a link.  The problem is when the two are plugged into each other, I don't get a link.

I have tried this with both a straight cable and a crossover cable.
