Hey guys, I'm new to BackTrack (about a week into it) but so far it's pretty cool...Anyways...

I've successfully done ARP poisoning using Ettercap on a linksys router but when I tried it on my other router (D-Link DIR-655) it won't poison! I've tried only poisoning one way and still nothing...I got on Google and read something about DNSSEC (DNS Security Extensions) and it talks about how new D-Links are able to block MITM attacks...

Basically what I'm asking is why and how does the D-Link block it (DNSSEC??) and why doesn't the Linksys? Also if this IS a security feature are there other ways around it?

P.S. Both routers are mine and I'm only asking for educational purposes...I find it entertaining.

Thanks!
