Thanks for your input, the second bit confused me slightly…
“You can create as green as you want, I want to remind you that you should create VLAN only when you need to create two or more logically separated networks using a single interface”
I am creating the VLANS on a linked pair of 24 port switches. In my Nethserver I have the single eth0 port on the Motherboard and 4 ports added in a 4 port NIC card, giving me 5 in total.
I will set one port for each zone, Green, Blue, Orange, Red. I assume Red would have to be a 192.168.0.x IP as my ISP has to be in this range at least for now as I am changing ISP’s soon and hope the new router from them will be more flexible.
Then I was going to make Green 10.0.1.x, Blue 10.0.2.x and Orange 10.0.3.x.
This would leave me with 1 spare Ethernet port and I was thinking about using this as a management LAN for my switches, the iLO on my HP server and possible access to the Nethserver as well as a range of IoT’s devices that communicate via radio (not WiFi) to a Raspberry Pi that in turn acts as a Gateway to my LAN.
I know this is over kill for home but I have proper cabling all around my House that I put in when we had the house rewired, two HP Micro servers and 2 decent switches and a collection of gadgets I want to connect up as well as all the home automation stuff.
