Putting it simply (before we have a look at the example) the ICMP - Redirect message occurs when a host sends a datagram (or packet) to its gateway (destination of this datagram is a different network), which in turn forwards the same datagram to the next gateway (next hop) and this second gateway is on the same network as the host. ICMP redirects are sent to define a better route/gateway to a destination. As you have to have an IP address in the same network as the gateway/exit for a route, the route will only be inserted in the routing table if all the following conditions are true: accept_redirects is set to 1

Jun 04, 2010 · In this scenario, our legitimate router gateway is 192.168.128.2, and our victim/target host is 192.168.128.128. We are going to spoof an ICMP redirect for the /32 host route 10.1.1.1, redirecting that address to the new gateway of 192.168.128.136. An ICMP redirect is a router's way of communicating that there is a better path out of this network or into another one than the one the host had chosen. In the example network , tristan has a route to the world through masq-gw and a route to 192.168.98.0/24 through isdn-router . From 192.168.7.254: icmp_seq=2 Redirect Host(New nexthop: ***.***.***.***)
