Trouble in getting the correct source IP for snmptrapd in zabbix kubernetes.

[aman kumar]

Hi ,

Thanks in advance !!

I am following the the url : "https://github.com/zabbix/zabbix-docker/blob/4.4/kubernetes.yaml"
to deploy the zabbix containers in a kubernetes,
I successfully deployed it in a kubernetes,

but, I am facing an issue , while sending snmptrap from external machine(outside our cluster) to the zabbix-server (via zabbix-snmptraps container),
actually , the ZBXTRAP showing different ip than external machine and that different ip is in the network segment of k8s pod-cidr,
,and i think ZBXTRAP ip is use in zabbix-server web-ui to monitor the snmptrap , so correct IP should be assign to the ZBXTRAP, which has to be external machine IP.

here, the logs I am getting in zabbix-snmptraps container
, 192.168.43.192 -- ZBXTRAP IP
172.19.8.104 -- external-machine IP

#cat snmptraps.log
20200303.114748 ZBXTRAP 192.168.43.192 SNMPv2-MIB::coldStart 0 (null) SNMP-COMMUNITY-MIB::snmpTrapAddress.0 172.19.8.104 SNMP-COMMUNITY-MIB::snmpTrapCommunity.0 public SNMPv2-MIB::snmpTrapEnterprise.0 SNMPv2-SMI::snmpModules
20200303.114748 ZBXTRAP 192.168.43.192 SNMPv2-MIB::coldStart 0 (null) SNMP-COMMUNITY-MIB::snmpTrapAddress.0 172.19.8.104 SNMP-COMMUNITY-MIB::snmpTrapCommunity.0 public SNMPv2-MIB::snmpTrapEnterprise.0 SNMPv2-SMI::snmpModules

NOTE: when IP using the IP "192.168.43.192" , it is working fine and showing the snmptrap log in zabbix-web gui , but when I am using the "172.19.8.104" IP is doesn't showing any log in zabbix-web.

kindly look into this problem , and let me know the work-around to solving this issue.


Thanks ,
Aman
