  • I would suggest more learn by doing approach. Learning OSI model etc is nice, but it is quite jargon :)

    Use some old PC as a server, and get some network cards into it, and use it as firewall/router. Route your home network/NAT/DNS/DCHP through it. Raspberry Pi’s are nice, but their hw is still bit limited.

    OPNSense is quite nice and easy free and open source firewall/router solution.

    If you want to add bit of flexibility, you can use some virtualization platform like VMware in to the machine, so that you can run OPNSense in it, with some other virtual servers.

    Then when you get things working, you can start looking in to VLAN’s, because they are quite important part of enterprise networking. Most cheap switches nowadays support VLAN’s out of the box.





  • World isn’t so black and white. Like I said they go hand-in-hand, both should be invested in. And all money should be taken away from fossil.

    I live in a country that will this year over produce green energy, which is awesome, because cheap green energy will enable many great things. But the challenge is that our energy price goes between 0 and a lot, because there just isn’t any tech to store it. Also green doesn’t produce heat, which in here Nordics causes that we need to create it somehow. Nuclear and CHP produce it as side effect.
