Hi,
I need help, with preserving SNMP trap IP address and hostname when
forwarding SNMP traps through snmptrapd
I got 10 servers behind a firewall and router, I have setup SNMP trap
forwarding and GET based on community string however,
snmptrapd rewrites trap headers, IPs and host name with SNMP Proxy server
information
[image: image.png]
snmptrapd.conf only configuration that was added
/etc/snmp/snmptrapd.conf
authCommunity net public
forward default 10.12.4.192 public
I was expecting to get trap with SRV1 information:
2019-04-10 08:52:46 SRV1.localhost [UDP: [192.168.0.20:36670
->[X.X.X.X]:162]:
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (14866232) 1 day,
17:17:42.32 SNMPv2-MIB::snmpTrapOID.0 = OID: SNMPv2-MIB::sysName
SNMPv2-MIB::sysName.0 = STRING: test trap from xxx
However, I am getting:
2019-04-10 08:52:46 snmp-proxy.localhost [UDP: [192.168.0.10:36670
->[X.X.X.X]:162]:
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (14866232) 1 day,
17:17:42.32 SNMPv2-MIB::snmpTrapOID.0 = OID: SNMPv2-MIB::sysName
SNMPv2-MIB::sysName.0 = STRING: test trap from xxx
I will appreciate any help
Thx and regards
