unfortunately my home system is a laptop and its in my backpack right here. I have been able to use something like logmein in the past.
I think a proxy might mess with the ability to connect to the local server tools I use to monitor customers connections. I think the MAC addresses are whats locked in on the system. when i plug my laptop into a wild ethernet cable it will connect fine. I just do basic tech and troubleshooting twice a week, so I dont have a lot of skill. I go to school for something else entirely.
