Good morning.
If anyone in the news was interested, i communicate that i have finished
developing
a simple ipv4 packet filter with nat/masquerading functionality.

Kernel programming encompasses these topics:

- Netlink sockets for user/kernel communication;
- Netfilter hook registration;
- getsockopt() function registration;
- Kernel module programming;
- Network programming (socket buffers, network functions...)
- /proc interface read/write example;
- kernel linked lists and related timers;
- ....

Userspace programming:

- Netlink communication (a simple netlink interface has been written);
- Pipes/semaphores for communication between parent and son processes;
- Networking functions;
- signals;
- unbuffered Input from terminal;
- ...
