Hi I got exactly the same problem and wrote a patch. You will need to
recompile net-snmp from sources though. Patches and instructions here -
sourceforge.net sourceforge.net They are for net-snmp-5.7.3, I didn't have
a chance to test them on 5.8 yet. Pik Master

If this is specific to only 10 servers, you could configure NAT on
snmp proxy for these 10 servers to do address spoofing?

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.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]
DISMAN-EVENT-MIB::sysUpTimeIns = 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]
DISMAN-EVENT-MIB::sysUpTimeIns = 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
