Hi and welcome to CNCzone.com,
I definitely don't know enough about your network questions to be of any help at all but have you emailed milltronics? You'll find out that their engineers monitor this site and so does the VP. I'm sure you'll get a response in a day or two, the guys at Milltronics have EXCELLENT customer service and I'm sure that type of service applies to owners of used equipment also. I can't give out their emails on here but I would do one of two things, either of which will work.
Either wait for an answer here or if you are in a rush, give milltronics a call and explain the situation at:
www.milltronics.net is their website in case you hadn't found it already.
Also, they're in the central time if that matters, I didn't look at your location...
