So, if you need your Receiver to listen on several IP interfaces, you have 
to register each of your local endpoints (IP:port) as a separate
transport at your SNMP engine. I've added this hint to a FAQ:

The short answer is - you should not have to know that. Please, find the 
long answer in the [newly added] hint in the FAQ:
