A few weeks before sent a mail regarding a prortocol handler problem.My problem was my protocol handler was not called during the arrival of packet.
But now i tried to accomplish the same task from the network card driver .
ie changed the code for 8139too.c by including a function my_fuction(sk_buff *).
This function is called from the beginning of rtl8139_start_xmit (struct sk_buff *skb, struct net_device *dev) of the driver . It works fine but what i want to do now is masq the ip address for
packets for 192.168.0.203 to 192.168.0.256 . the functions compares each packets
skb->nh.iph->daddr fileld with 192.168.0.203 and masqs it .But when i am pinging to 203 i should get the response from 253 , but its not going well for the time . .I dont know whether it will work or not any body please give an advice.I know iptables is best for these type of practise ,but Just for my sake i wanted to try it out.i am using redhat 2.4
regards shyamjith
