Subnet mask and multiple subnets via 1 router

[Jaganmohini]

I have a router that services 192.168.10.1/24
I want to rip the LAN into 4 sub nets:
192.168.10.1/26
192.168.10.65/26
192.168.10.120/26
192.168.10.155/26
so that no sub net can speak to each other but each sub net make use of the router that is 192.168.10.1There is no problem in the first sub net but when entered the router address into the additional sub nets as the default gateway windows complain that( router isn't on the similar sub net) but let me proceed my work is there any problem doing this?

According to me may be the Address Resolution Protocol proxies the routers address diagonally the V LAN's or V LAN switch may be having some layer 3 functionality. In spite of whether it works or not, the arrangement you illustrate is decisively, wrongly applied. Each interrelated network section should have a layer 3 mechanism and a default gateway that's within its own subnet. Anomalies and miss configurations turn into security risks and/or network problems.

If by having PC not speak to each other means not transmit to each other to keep away from LAN traffic, you can easily achieve your task by using VLAN's. At the most basic level, a VLAN is not anything more than a broadcast domain, sense that it is a Layer 2 unit. What tends to pitch people is that a VLAN is in reality a broadcast domain configured on switches on a port-by-port basis. A broadcast completed by a system on port 1 will only go to systems linked on those first 5 ports, and is not seen by those on the last six ports. In this way, I’ve used the switch to describe two unlike broadcast domains."

I would think the protected stake is to have a layer 3 routing device separating them. If you assign it a /24 your subnet mask would be inaccurate for your scenario. I don't know how to get to an IP address whose previous octet is 65 or 193 other than to transmit if using /24. If you’re DHCP on every subnet is a server, you can add another NIC to it and locate up routing?
