[SOLVED] Packet Redirection

gowtham92 · 12-06-2011, 12:35 AM

HI LQ,

I need to redirect packets from one system to other system in a same network.

suppose if a system (say A) receives large amount of attack packets from(say B) , it needs to redirect those packets to some other system (say C) which is in the same network.

Pls help me to implement this.

Well what specifically do you want to know..

There isn't enough information in your post to really be able to help.

What are you trying to acheive?

How are you going to differentiate between 'attack packets' and the other sort (non-attack, presumably) of packets? And why do you want to redirect rather than just drop them?

external interface = eth1
protocol = tcp
port = 80
server = 192.168.100.1
another computer= 192.168.100.200

iptables -t nat -A PREROUITNG -i eth1 -d 192.168.100.1 -p tcp --dport 80 -j DNAT --to 192.168.100.200
