There are two good books that you might find useful - 

1. Understanding Linux Network Internals - Christian Benvenuti
2. The Linux TCP/IP stack - Networking for Embedded Systems - Thomas F. Herbert

I am trying to understand the implementation of linux 2.4 and linux 2.6's networking (IPV4) . Can anyone give me some idea/pointers about some of the good resources/whitepapers available in the market to understand the same. If there is any document that mention the changes between the implementation of networking in  2.4 & 2.6

I am also trying to write a simple program(preferably a userspace application) which captures all the incoming and outgoing packets of a particular machine (preferably at PREROUTING stage), then according to the SRC/DST addresses, changes the IP address of some of the packets and then reinject it back into the local IP stack. I am able to do that in  2.4 kernel by using libipq and ip_tables but that prog is not running in 2.6 kernel. (It hits at ip_route_BUG). Any idea or code snippet will be really appreciated.
