Let me try to explain the situation.
Into my local network I have a Linux Ubuntu VM running Zabbix Server and everithing is okay from internal side.
All computers are able to access Zabbix GUI from address 192.168.100.20:80/zabbix.
The issue happens when I try to configure a Firewall and DNAT rule to gave access to this same server through the address https://multipoint.dyndns.org:8080/zabbix.
Also, I've tried to use the current ISP IP Address to do the same access tests, but no success, so the issue is not related to DDNS service.
I already configured the host IP as shown below:
Also, I've configured HTTP 8080 service as below:
I've created the firewall rule to allow communication through 8080 port as below:
And also, I've created DNAT rules to forward the communication from 8080 port to 80 port on Zabbix Server host:
I've tried to configure DNAT rules to communicate trhough 80 port with no translation, but still have no success.
Please, could someone advise?
