There is an older Watchguard 3000 series at a client site that uses DVCP on WSM 7.5 (I know, it's old). For the old edges, this was a pretty easy thing to setup. There isn't much configuration on the 3000 side and even less on the edge watchguard (we used to use x20s). Now there is a new branch office and we have a new XTM 22... any special tricks to getting the tunnel to come up?? Haven't had any luck yet... maybe they won't work together through DVCP.
