Some earlier versions had problems with this. The current version
(2.0.1) uses the IP address from the UDP header:

Please make sure you are using 2.0.*. If the problem still exists,
send me an example script that will reproduce this error here. It
would also be helpful to include debug output from scotty (turn `snmp
watch on').
