My work document for my Mikrotiks
(Also for my friend Vincent, with a similar setup.)

I’m going to collect information on this page for below changes.

WIFI

  • Access list connections only
  • Default forward – only certain clients
  • Guest network – better setup.
    I’ve got a folkband guest network right now and
    a captive portal AP on my internet router. (Outside my network)
    This is for colleagues of Coline.
  • Vlan for certain clients

Zerotier

  • Network routing
  • Security

IOT

Move all clients to own vlan
New or better VLAN setup

  • Redo Guest network
  • IOT Vlan
  • Manage Vlan better setup
  • Lab – a redo because of changes in DMZ

Mikrotik

Switches and access-points

Today i got my RB4011 ! Wooot!

Total tally

  • MikroTik CRS305-1G-4S+IN – Lab
  • MikroTik RB2011UiAS-RM – Office
  • MikroTik hAP AC2 – Studio
  • MikroTik CRS109-8G-1S-2HnD-IN – Attic
  • MikroTik RB4011iGS+5HacQ2HnD-IN – Livingroom
  • NEW (2022-04-02) crs125-24g-1s-in (2022-04-02)

To replace .. 4 SLM2008 and a TPLink switch 🙂

How much fun is this! .. A display on a switch!

I’ll be posting something about connecting an arduino to the serial console using a tcp server later.

Mikrotiks are all you can eat .. And there is a lot of functionality. One of the main features (besides being switches and routers)

  • Openvpn server
  • DIY display connect
  • Proxy
  • Today Vincent mentioned Mqtt plugin (2022-apr-6)
  • https://help.mikrotik.com/docs/display/ROS/Packet+Sniffer sounds interesting also

Installing extra packages

  • Download correct package zip from ( https://mikrotik.com/download )
  • Extract and use file upload
  • Reboot your mikrotik

Mikrotik Guest Network

I’ve got several AccessPoints in my network.
Using a roaming setup, clients can connect to strongest AP.

For our Folkband i’ve setup same.
With the exception of those clients only being able to connect to the Internet, and not the rest of my Network

  • Virtual Access Point
  • Own subnet
  • dhcp server only for this access point
  • NAT and Firewall rules for access limitation
