Cisco 7200 VXR & Comcast Metro Ethernet Speed issues
We moved to our new headquarters and have Comcast's Metro Ethernet installed.
We noticed that we weren't getting our rated speeds in the server room, and plugging a laptop into the Comcast device directly, setting Flow Control to off, and the port negotiation to 100 Full Duplex, the laptop pulls a full 100/100 connection.
We tried that same setup in the server room with the feed coming up from the Comcast equipment, and again, the line is delivering 100/100. The minute we connect it to the Cisco 7200 VXR, speeds plummet to 1.5 Mbps on both the up and downstream.
Our Cisco guy on-site says he's used the 7200 VXR with connections much faster than ours, so he's not sure why we're having such a hard time. In every case, latency is phenomenal, often registering under 10ms to just about anywhere within three states, and not more than 25-30 to New York.
Anyone have any suggestions?

It doesn't matter if we match Comcast's connection - we had been set to 100 Full Duplex, and when we try Auto, we would get 100 Half Duplex.
The Network is set up like this:
Comcast - > Cisco 7200 VXR -> Cisco ASA 5510 -> Dell Power Connect 6248 -> Network
We do have a DMZ switch running on a Cisco Catalyst 2960, which is connected directly to the DMZ interface on the ASA.

If possible hard code both sides to 100 Mbps Full Duplex.
