### Option: Server
#       List of comma delimited IP addresses (or hostnames) of Zabbix servers.
#       Incoming connections will be accepted only from the hosts listed here.
#       If IPv6 support is enabled then '127.0.0.1', '::127.0.0.1', '::ffff:127.0.0.1' are treated equally.
#
# Mandatory: no

Allow Firewall

ปกติแล้วหลังจากที่ิติดตั้ง zabbix agent มันจะ allow port ให้อัตโนมัติ แต่ถ้ายังไม่ชัวร์ ให้ลองตรวจสอบดูอีกรอบ

Iptables

iptables -A INPUT -p tcp -m tcp --dport 10050 -j ACCEPT

iptables-save > /etc/iptables/rules.v4

Ubuntu

sudo ufw allow 10050/tcp

RedHat / Centos

firewall-cmd --new-zone=zabbix --permanent

firewall-cmd --permanent --zone=zabbix --add-port=10050/tcp

firewall-cmd --reload
