Is there a way to set LARGE_NAT in the env prior to calling build.sh without mucking with the source tree? This shows a 3 year old request so such an ability is desirable: http://mail-index.netbsd.org/netbsd-users/2004/08/06/0007.html Yet the #undef remains, now at line 31 in src/sys/dist/ipf/netinet/ip_nat.h. Is this because there is a better/different way to select that feature? peter
