Networking :: TUN/TAP Drivers !

I wold like to set up a VPN on my computer unning DSL. I will be using Hamachi (www.hamachi.cc) as the VPN client.

The problem is, Hamachi needs the TUN/Tap driver to work. (no duh) But When I try to install this driver, its looks for the linux kernel source in /usr/src/linux There is no kernel source in this location, as this dir doesnt even exist ../src/linux does not exist, /usr does. Now i have went a downloaded the kernel source ( i believe it is the source) here

==> http://www.kernel.org/pub/linux/kernel/v2.4/

Now i took the "linux-2.4.26.tar.gz" and unpacked it into the /usr/src/linux folder. But TUN/TAP still dont see it.

What am I doing wrong?
Thx, Snippet
