SNMP Trap Iptables problem

[DieterV]

Dear community,

I followed this guide

https://www.zabbix.org/wiki/Start_wi...raps_in_Zabbix

to configure SNMP traps on my zabbix 2.2.2 on CentOS 6.5.

It works as long as I don't turn on my iptables.
If I do start iptables (with port 162 accepted), the traps isn't shown in zabbix or saved in the tmp file.

But I tested and I'm sure that it arrives with UDP at port 162.
I did reset my counters of my iptables and saw that every time I did sent a trap, the rule (of port 162) was chosen, which means it passes the iptables.

Please help

Any help

Disappointing

Take a look at example

Especially on a couple of lines:

######## Allow SNMP request and SNMP trap packets.
-A RH-Firewall-1-INPUT -p udp --dport 161 -j ACCEPT
-A RH-Firewall-1-INPUT -p udp --dport 162 -j ACCEPT

May be it can give you some ideas.
