I just want to ask, can a low-end hardware router with NAT (linke RT314) be able to protect the network form being traffic ewdirected? I know that BlackIce can detect such attack and block that IP. If hardware router can't protect this kind of attack, people could easily sniff the packets to and from my network..... Could someone give me an answer on this? Thanks
 
A so-called "ARP attack" can only happen on your LAN. So keep people from hacking into a host on your LAN, and you are protected against the ARP attack.
 
Another is called the ICMP Redirect attack. This exploits the Redirect bit within an ICMP packet. This type of attack is refered to as a Distributed DoS attack (DDoS). There is really no way of protecting yoursefl from this attack except for denying all ICMP traffic either on your router or with your firewall.
