That is exactly the bug that has been fixed now.

That will bind all outbound SNMP requests to local port 162 as well, instead 
of local port 161 as before.  TIdSNMP has been fixed to use both ports now 
(TIdSNMP has a separate TrapPort property, afterall - it just was not 
previoiusly using it for anything).  As such, you need to update your code 
accordingly:


{code:delphi}
procedure TfrmMain.bbtStartClick(Sender: TObject);
begin
  snmp.TrapPort := 162; // <-- do not use BoundPort for traps!
  ...
end;
{code}
