OK, it's that I have a problem at the receiver discarding the packet, and it is a pretty obscure system, but I now sent to another host and snooping there shows that the checksum is OK. I'm suprised that a highlayer thing such as IP checksum is calculated at such a low layer. > If your application binds to an address that happens to be configured on > interface A, but the forwarding table dictates that the destination is > reachable through interface B, then your packet will go out of interface > B. I suspect that's why you need to snoop on e1000g0 here. Yes, I had forgotten this, thanks for the help Rob
