iptables configuration

[wombat613]

I must have a small error in my iptables (Centos 7 client)

if I service iptables stop I can communicate with the zabbix agent, put iptables back on, and no communication, so there has to be a mini error

Please, keep in mind that all rules works as it written in file.
So, after instruction which have a word REJECT - no any rules working.
Move your rules about ports 10050 & 10051 before REJECT instructions.
