Introduction to complex network structures.

Hello everyone

I'm using OPNsense from few mounts now and I love it! But I want to make my home network just a little bit more organized and I need your help because I'm lost...

Recently I've manage to get HP ProCurve 2626 (J4900C) for $10 from eBay and after resurrecting one old HP 6005 Pro (AMD ATHLON II X4 645, 16GB Ram, 2x2TB HDDs) I'm ready to start!

That is old hardware - I know that, also there will be issues like old firmware, etc. - I know that also - but for the moment I can't invest any money to make it better, so I need to work with what I have.

So after few days of cleaning dust, changing thermal paste and preparing small place where to put everything I want to make something which will work and will be practical, so here is my idea:

Proxmox as main OS
OPNsense as guest VM
Another VM for few lightweight WEB apps เล่นคาสิโนบนมือถือ

So far, so good but here is my problem: My machine have only one NIC and I want to use it for so called "router on a stick"

What is my topology:

ISP up-link enters my apartment - it's a cat6 cable without modem/router and this cable is connected to one of the Gbe ports of my switch
the host machine is connected to the second Gbe port of the switch
few ports are occupied by dummy APs, 2 PC and 3 SBC's

What is my issue:
I don't know how to set all VLANs and briges correctly so the OPNsense VM to act as normal router so, all hardwired/wireless devices to get their IP from OPNsense's DHCP, and all other VMs to be able to access internet also.


So I ask for advice and ideas of everyone.

Thanks to everyone who offered the idea.

Have a look at this article https://www.theregister.co.uk/2017/06/30/vlans_at_20/

You'll want to connect your ISP link to an untagged port on the external VLAN, and trunk both your external and internal VLAN to the hypervisor. Proxmox will need to connect each VLAN to a separate vNIC.
