nemesis + icmp redirect

[zahizahir]

Hi.
I'm trying to do mitm with using icmp redirect and nemesis. it's my configuration:
VICTIM - 192.168.1.117 mac: 11:11:11...11
Attacerk - 192.168.1.133 mac 22:22...22
Gateway - 192.168.1.1 mac 33:33:....:33

and how i;ve created a packet:

nemesis icmp -v -d eth0 -i 5 -c 1 -G 192.168.1.133 -qR -S 192.168.1.1 -D 192.168.1.117 -H 33:33:33:33:33:33 -M 22:22:22:22:22:22 -B 192.168.1.117 -b 74.125.39.99 -p 6

Packet is injected to the network but a checksum of icmp and ip protocol within icmp are incorrect ( using wireshark here) so packet is drop by the victim. Here it's a link with printscreen with wireshark log:

What am I doing wrong ?
