Configuring GUP and remote locations with identical subnets
I want to try using a GUP at a couple of locations but I'm not sure it is possible (or efficient) for my situation from how I understand how you configure GUPs and subnets. I haven't been able to come across anyone that has this situation. We are running SEP 12.1.2015
I have about ten remote sites on slow connections that are basically behind routers of the home grade variety using it's DHCP and subnets of the 192.168.x.x (I did not set these up). They are not on a domain and usually don't connect back in to our main campus private network(10.24.x.x). Most of the remote sites have very few computers and thus don't have a bandwidth issue. About two or three locations have about a dozen computers that I would like to utilize a GUP at each one because it just makes sense for these spots.
But because the each site basically uses the same subnet of 192.168.0.x or 192.168.1.x Computers at sites that aren't supposed to use a GUP will think they are a part of the same subnet for the GUP. Or even someone takes a laptop and connects it to their home network which would probably have the same subnet.
In my example below, I made up something similar to what I have going on a smaller scale with a purposed 'Make GUP' for a couple of sites.
|PC1 Make GUP||192.168.1.2|
|PC5 Make GUP||192.168.1.2|
I know you can set a time out if it can't get to a GUP and then it will fall back to SEPM or something like that. But I would think that would make unnecessary network traffic and take too long for a timeout. Is it possible to do this or a waste of time?
