Will the N5200B Pro support two different subnets without routing between the two? I have six XP Pro PCs with vision systems that will store their images on the N5200B via one subnet and users will view these images via a different subnet. I want to keep the vision PCs isolated from the general PC population due to viruses, OS patches, etc.
Also, for this configuration, I do not believe I will use the failover or load balancing features. Will this cause any problems?
What you want is possible, but you would not do that on the N5200, this is something that is done on your routers themselves and not on the N5200. The N5200 is only an available server on your network, to do routing as you stated, you would need to do this on your routers themselves.
I want to maintain the separation of the vision system PCs on their own subnet from the users who are on the main office subnet; therfore, I do NOT think I want to route between the two subnets with the N5200B PRO. Otherwise, is this configuration correct?
The N5200 has 2 network interfaces, 1x LAN and 1x WAN. You can set both interfaces on different subnets, i.e. 1 on 192.168.1.x and 1 on 10.x.x.x.
There is an option called 'IP sharing' wich you can enable to route both subnets. So, ofcourse, when disabled traffic will not be forwarded from one network to another. Obviously when you use these settings, link aggregation cannot be used.
Probably you'll think of that, but if you don't want users to exchange files between both networks, you have to set permissions to the folders on your N5200. Authentication method is also something to think about (N5200 joins 1 AD and/or uses local authentication).
Hopefully this will answer your question. If needed, maybe other forum-users can also help ...
