Presumably this runs as an AgentX subagent - yes?

Which API are you using to generate the trap? In particular, are you
using SNMPv1 or SNMPv2 syntax? If the latter, try appending a
'snmpTrapAddress' varbind to the payload list, with the address you
want to use. I'm not sure whether that will do the trick or not, but
it's worth a try.
