How to see frontend Zabbix server through the Internet without opening the Firewall?

[alexisvieiro]

Hello.

I am in need of a solution to be able to view the zabbix frontend over the internet. The problem is that for a security issue, I cannot touch the client's router / firewall to allow connections from outside.

I thought about using a Active Zabbix Proxy on the client and the Zabbix Server in my company, but if the link goes down, the alarms and triggers would not work.
I also thought of using some kind of database replication, from the client's zabbix server, to my own zabbix server, but I'm not sure if this would work.
Another possibility was to use Grafana, but I think I have to open some port for connections from outside.

Any help or tutorial helps me. What I find does not convince me.

Thank you.

I would look into a vpn of some form. There are all kinds of software based vpn's out there. My personal choice for something like this is zerotier. its a server less vpn that can be put on almost any host imaginable. you just put the client on the two ends (zabbix server and device you want to access it from) make sure they are linked to the same account, and then you should be able to access it as normal using the ip address of the vpn. you can even set static ip addresses online. This way, you don't have to make physical changes to your client's firewall or router.

I really appreciate your help.
I had the wrong idea that to establish a VPN you had to configure the router. But from what I found out, the router sees it as a typical communication.
