Broadband install: need to change IP ranges
Okay guys, newbie question for the geniuses:
New broadband installation is imminent, only I have been told that because our new firewall & filtering is hosted externally (by new ISP) I am going to have change our entire network address range so that it doesn't conflict with another schools network.
(Never thought this would be a problem being a private range, how wrong I was...)
For someone who's never done anything like this before, what's the best way of going about making all of these changes?
Are there any things I need to really watch out for?
Any advice anyone could give would be much appreciated!
