Setting up an OpenVPN server on MikroTik

One day some mobile operators started blocking ports to L2TP servers, so I set up a more secure OpenVPN server on MikroTik.

How to configure MikroTik CAPsMAN v2

For example, I will configure CAPsMAN v2 on MikroTik PowerBox Pro with MikroTik cAP ac access points (RBcAPGi-5acD2nD), instead of PowerBox Pro you can use, for example, MikroTik hEX PoE (RB960PGS), they have 4 POE Out ports, you can connect 2 access points to one POE port, the recommended cable length is up to 80 m, so POE can power 8 access points, but you need a more powerful power supply than the one included, for example, I remember in the PowerBox Pro manual it says that at 24V 1A on the POE port, at 48V 0.5A, so you need a 24V 6A or 8A power supply. If there is not enough current for the access points, then they will reboot when, for example, the CPU is more loaded. Thanks to CAPsMAN, by changing the configuration of wireless interfaces on the main device, such as password, frequencies, etc., they are changed on all access points automatically.

In my case, it was perfect for an educational institution, there is a combo port on the back wall, which I configured as a WAN and the Internet was connected to it (from GPON ONU with a twisted pair cable), and managed switches were connected to the front 5 SFP ports.

How to see Wi-Fi password on MikroTik

If you look at the password in the Wireless – Security Profiles menu in RouterOS, then it is hidden behind the symbols and can only be changed, so I will show an example of how you can see it.

MicroTik. How to change LAN IP addresses

I will give an example of changing the range of IP addresses for the local network. The default is 192.168.88.0/24, but there are times when an organization uses a different subnet and needs to install a new MikroTik, or when multiple MikroTik devices are used on the same network, or users use multiple MikroTik routers connected in a chain.
