ARP poisoning is a destructive means of gathering traffic. If you are
concerned at all about the performance/usability of your network do not use
ARP poisoning.

A better bet is to use a span/mirrored port on a managed switch. Setting up
a linux box as an inline router/capture device would work as well. If all
else fails you can use a hub, or static ARP table entries.

Using ARP poisoning on a network you control is like using a crowbar to
enter your own house.

I'm using arp poisoning to grab MSN traffice and MNS keeps getting
logged out or the internet keeps dropping off - laptop hooked up to
802.11G router. If I re-route my internet through my Linux server
(router to server to cable modem) and just grab packets there will I
experience the same problems? I know there will be a lot less traffic
but If its going to degrade my internet/network performance its just
now worth it.
