  • The poster i was responding to equated subnetting to vlans. I might have misunderstood what they meant though. It sounded like they wanted to use the same subnet per vlan, which wont work if you want them routed in the same gateway.

    Reading it again they make it sound like you can’t subnet all of these networks on a switch without vlan, which you definitely can. I could for example connect 4 different devices on the subnet 192 168.10.x/24 and have them reach each other. I could also connect 4 more devices in the same switch but on a different network 192.168.20.x/24 and it would work.








  • It has to do with link priority on the server. You’d imagine that a server that receives a packet that has a return address on the same subnet as it self logically would use that interface instead.

    A similar thing happens in switches. For example if you have two vlans on a switch and both vlans have an ip assigned, connect a computer to one of the vlans. You will only be able to reach the switch on the non-routed connection. Even if you also are allowed to reach the second vlan through a router/Firewall.
