Subject: IPPROTO_IPDIVERT undeclared error in natd

I'm happy to say that I am making progress with this...but still having
trouble. Trying to make the natd binaries..I finally got my in_cksum.h
and got passed that hurdle....but now I am getting an undeclared error
in the natd.c source. I get the following error at compilation:

===> alias

===> natd

cc -O -Wall -g -I../alias   -c natd.c

natd.c: In function `main':

natd.c:178: `IPPROTO_DIVERT' undeclared (first use this function)

natd.c:178: (Each undeclared identifier is reported only once

natd.c:178: for each function it appears in.)

*** Error code 1



Stop.

*** Error code 1



Stop.                   

This is the source code that is referring to IPPROTO_IPDIVERT 

/*

 * Create divert sockets. Use only one socket if -p was specified

 * on command line. Otherwise, create separate sockets for

 * outgoing and incoming connnections.

 */

        if (inOutPort) {



                divertInOut = socket (PF_INET, SOCK_RAW,
IPPROTO_DIVERT);       
                if (divertInOut == -1)

                        Quit ("Unable to create divert socket.");



                divertIn  = -1;

                divertOut = -1; 

Where should this have been declared? I have recompiled my kernel with
the IP_FIREWALL And IP_DIVERT options and am running Walnut Creek
FreeBSD 2.1.6-RELEASE #0

Mark.
