Today I installed a new router for the DMT system, with the latest version of Vyatta Core - 6.5R1.  It is functionally identical to the old system, but we are trying to standardize on a hw/sw config for these systems in the MSR, and this is the first step.  There should be no visible difference in accessing the DMT machines from off site (unless you tried today while I was in the middle of swapping things around).
