Cannot telnet 10051 externally, internal works fine
Hello Everyone -- I just setup my first Zabbix server running on Ubuntu 18.04 yesterday. After a very large learning curve with Linux, Apache and this application I am finally able to collect data, but only from the local server itself.
I am in the process of installing the Zabbix Agent on some Windows client machines but I noticed my logs show I am having an issue connecting to my server through port 10051 TCP over WAN. I have opened the port on my server via UFW (sudo ufw allow 10051/tcp), I can telnet it locally, but when I try externally I am not able to and get timeouts. I of course can telnet every other port I am using over the WAN without any issues.
If I had to guess I need to somehow forward external port requests to Zabbix? Or is there another method I should consider?
