I have a problem I've never seen before.
First the layout:
I have multiple LANs (2 maybe 3) that I want to connect together via VPN tunnel. The goal is to provide remote back up of critical files in an automated fashion for each location using Ready NAS file servers and to allow other benifets of connected networks.
To do this I need to change the default IP schema, 192.168.0.1, to to something that will accomodate multiple subnets.
The problem is that when I change the 3rd byte to something other than 0 the PC's on the network stop talking to one another. I can't ping from PC to PC. The PC's will ping other devices on the network, printers, color Copier/printers, and even the Mac computers and NAS devices. For the most part this would not cause a problem except that one PC needs to be able to output graphics files to a PC based RIP.
I have reset the router to Factory default and changed to a back up router and both act the same. Every thing is fine if the IP is 192.168.0.1 but stops working if I change it to 192.168.x.1 where x is other than 0.
I am under the understanding that for multiple subnets I can't use a 0 for the third IP byte if my SN Mask is 255.255.(0-254).0 only if it is 255.255.255.0 (single subnet) .
If your first question is did I remember to change the IP on the respective PC's each time? The answer is yes.
Anybody seen this before and/or have an idea how to fix?
Maybe you can elaborate more on what you are trying to do and what mask you are actually using or trying to use .
