which method are you using to send traps? If you use the
NotificationOriginator, the traps will have the address of the interface
that is used to send the trap as source address.

1) You can use the Snmp::trap() member function directly. You just have
to create the Snmp object with the address of the desired interface.

2) If all of the used IP addresses are valid for sending traps to the
agents, you could change the NotificationOriginator class to use the
socket of the Snmpx object of the RequestList [the one that is set using
reqList->set_snmp(&snmp) in main()].
