Hi Jan,
Thanks a lot for the patch. It fixed the agent address inside the UDP payload.
The '[snmp] clientaddr 192.168.1.1' in my snmpd.conf doesn't fix the IP
address in the UDP packet in my case. For example, the outgoing interface IP
for the trap is 172.16.1.1, but I expect the ip address in the UDP packet of
the trap to be 192.168.1.1. Even if I configured with '[snmp] clientaddr
192.168.1.1', I can see that the source IP is still 172.16.1.1. I wonder it
might be the snmp.conf file is not defined.
Is there a easy way to get around with this?
Cheers, Henry
