in reply to Re: ARP poisoning and redirection
in thread ARP poisoning and redirection

Well thank you, those ideas will be used in the next round of testing today. Once its all over I'll put a completed module targeted for that (rare) kind of broken playground in CUFP :)
With a list of limitations of course... Update:
this change solved part of the problem and the code should run without issues on a hub, now it seems that the router is blocking gratuitous arp replies, directed or not. This will require more investigation but I suppose a simple hub instead of a router/switch would let those through.

One possible explanation that I would love anyone in the know to confirm or deny is the following:<br
Even though arp is stateless the router keeps tracks of arp requests and replies and will only let a reply through if it has been preceded by a request AND|OR is agreeing with its own arp table
