Good morning. I am looking at restructuring our small business network. I would like to achieve this by essentially creating contiguous subnets such as those in a 192.168.1.0/20 or 192.168.1.0/21 network. These would allow me to structure devices on 192.168.1.0, 192.168.2.0, 192.168.3.0 and so on while allowing these devices to still talk/communicate to each other, this is essential.
One problem/concern I am running into or looking at is in the RV016 setup tab/network for the LAN setting you can enter the device (router) ip address, and then select the SNM from a pull down menu, however the only SNM's available are predetermined 255.255.255 class C 0,128,192,224,240,248, and 252 masks where I am looking to create a classless system for aggregation.
Now I know also in setup I can add multiple subnets, I have tried experimenting with this, but what seems to be happening is windows/pc machines ,when on an additional subnet that has been added to the router, can ping devices in the building, but cannot see/talk to those devices. For example, windows pc 192.168.2.3 can ping 192.168.1.36 but cannot talk to 192.168.1.36. At least this is what I experienced with a quick test yesterday.
Is there a way to use CIDR with the RV016? Can this be achieved perhaps through advanced routing in the setup section? I already manually assign addresses to all of the devices within the company/organization so everyone has a static ip even though DHCP is running. If this can be done with advanced routing, what would the Destination IP be? If this can't be done this way, is there another way to achieve this with either a different device or more devices? I am new to subnetting but have been reading up on it and did a Cisco workbook and a little research on the net so I have a decent understand of addressing in regards to subnetting. CIDR is slightly confusing but seems to be the solution that I am looking for. Thank you for your help!
