It isn't quite clear what you mean, but presuming you mean "make a change to the FreeBSD kernel that you use" then: 1) First learn how to recompile your kernel. You can get details from the FreeBSD handbook (http://www.freebsd.org/handbook/). 2) Look under /usr/src/sys for the kernel source code. The main bit is in /usr/src/sys/kern, networking lives under /usr/src/sys/net* and so on. 3) Change the code you want and then recompie the kernel. Remember to keep an old kernel around incase you make a mistake. David.
