Freeing Ports for External Access

Troubleshooting
1

I released the following ports on my Mikrotik:
UDP: 161,162,514,6559
TCP: 80,443,514,6556,8000

My question, for me to monitor a host, do I need a local server that will communicate with mine or can I get the agent to communicate directly with my central server, as I have clients from a business that only has two hosts for I monitor, in this case they don’t have a server on site, I needed to communicate directly with the checkmk server, but even releasing the ports on my router the agent is not communicating. In other words, I need an external host, outside of my network, to be able to communicate directly with my server, would I be able to do this?

By default in Checkmk the server always contacts the agents and not! the agent the server. Therefore you will need to configure port-forwarding on your router, use the Cloud edition which contains a Push agent where the agent actually sends the data to the server or you will need to implement a solution like explained here:

168.194.212.160 seems to be a public IP address (please not share these if you can avoid id)

This means you need to allow your checkmk server on 168.194.212.160 to talk to your private 172.16.34.130 client.

I would strongly not recommend that. Opening your router for the outside world is a bad idea, and open all these ports you mention is not intelligent.

Best way would be to setup a VPN from the network you have your checkmk server to your local network.
