Please provide more details - attach a ostinato stream with the offending packet

Hi,
 Apparently when de-selecting the checksum's check-box ostinato does
compute the igmp checksum correctly.
 Sorry for the 'false alarm'.
Another issue arose: 'Router alert option' -- is it supported in ostinato?

Checksums are calculated automatically - you click the checkbox only to 
override it.

IP Options (including Router alert option) is currently not configurable 
directly in the IP protocol config widget. You can use a hexdump proto for your 
IP options (Router alert or any other) and modify the IP header length field 
manually. 

Raise an enhancement issue on the tracker to support IP options in the IPv4 
config widget
