I am NOT using the OpenWrt kernel. I am using the Ubiquiti 4.14 kernel, and building from main.
Package kmod-ipt-nat is missing dependencies for the following libraries:
nf_nat_ipv4.ko
nf_nat_redirect.ko
These are created by the kernel (~/kernel_e50/) but are not copied into build_dir/target-mipsel_24kc_musl/linux-ramips_mt7621/packages/ipkg-mipsel_24kc/kmod-ipt-nat/lib/modules/4.14.54-UBNT/:
~/kernel_e50/net/ipv4/netfilter/nf_nat_ipv4.ko
