Hi Jan,
Thanks a lot for your help.
I have put the '[snmp] clientaddr' option to set source address of UDP packet
with the trap as in the following in my snmpd.conf file:
[snmp]
clientaddr 192.168.1.1
[snmpd]
.....(The rest of commands in my snmpd.conf file)
But when I capture the trap packet, it still shows the IP address of the
outgoing interface. Did i do something wrong in my config file?
Best regards,
Henry
