My current setup is following: 192.168.1.x is the main zone behind a NAT router of my internet provider
192.168.2.x is another zone, where all my devices live - they are behind another NAT router, which allows much more configuration etc. If I need to connect to any device on the 1x network, the traffic goes through the router flawlessly.
I would like to create another subnet - namely 192.168.3.x to better organise my NAS traffic and interfaces.
However, if I set up the subnet mask as 255.255.0.0, I will not be able to go through the router and access the 1.x network easily.
At this moment, I will have the default mask at 255.255.0.0, which works fine, and then I have a single machine that has hard-coded value at 255.255.255.0, which forces the 1x through the router.
I would much rather have it all work seamlessly, what would be the best course of action? I was thinking about possibly re-numbering the first network to 10.x.x.x range, which would make things simpler but is there any other, easier way that it all could be achieved?
To sum up - the main problem is, that in order to allow 192.168.2.x and 192.168.3.x addresses to communicate together, the net mask needs to be 255.255.0.0, which puts also the 192.168.1.x onto the same subnet in the eyes of the network adapters (even though it is actually a separate network). What I would like is to come up with a netmask that would include 2.x and 3.x onto the same net but exclude the 1.x. Is it possible?
