did you actually completely rebuild the kernel, or just config it with
options gateway and re-make?

The behaviour of the GATEWAY option is (in 1.3-branch and -current):

#ifndef IPFORWARDING
#ifdef GATEWAY
#define IPFORWARDING    1       /* forward IP packets not for us */
#else /* GATEWAY */
#define IPFORWARDING    0       /* don't forward IP packets not for us
#*/
#endif /* GATEWAY */
#endif /* IPFORWARDING */
[ ... ]
int     ipforwarding = IPFORWARDING;


so if you turn on GATEWAY, you really should _not_ need to sysctl
net.inet.ip.forwarding.
