I have a machine on which I have an applications that sends multicast

checksum on the eth device the packets arrive with the proper checksum.
Where is the client? On the same machine or behind a PPP link?
The clients are behind the ppp links.
As far as IGMP and multicast handling everything works, the packets are
even forwarded over the ppp links but they arrive to the client with a
bad checksum. I don't have the trace in front of me but I believe it was
the UDP checksum that failed.
