As far as I understand the kernel facility nftables exists in the kernel that comes with Ubuntu 14.04. As is proven by the following two commands:

# grep -E '(NF_TABLES|NFT_)' /boot/config-$(uname -r)

CONFIG_NF_TABLES=m

CONFIG_NFT_EXTHDR=m

CONFIG_NFT_META=m

CONFIG_NFT_CT=m

CONFIG_NFT_RBTREE=m

CONFIG_NFT_HASH=m

CONFIG_NFT_COUNTER=m

CONFIG_NFT_LOG=m

CONFIG_NFT_LIMIT=m

CONFIG_NFT_NAT=m

CONFIG_NFT_COMPAT=m

CONFIG_NF_TABLES_IPV4=m

CONFIG_NFT_REJECT_IPV4=m

CONFIG_NFT_CHAIN_ROUTE_IPV4=m

CONFIG_NFT_CHAIN_NAT_IPV4=m

CONFIG_NF_TABLES_ARP=m

CONFIG_NF_TABLES_IPV6=m

CONFIG_NFT_CHAIN_ROUTE_IPV6=m

CONFIG_NFT_CHAIN_NAT_IPV6=m

CONFIG_NF_TABLES_BRIDGE=m

# lsmod |grep nf

nf_conntrack_ipv4      15012  1

nf_defrag_ipv4         12758  1 nf_conntrack_ipv4

nf_nat_ipv4            13263  1 iptable_nat

nf_nat                 21798  3 ipt_MASQUERADE,nf_nat_ipv4,iptable_nat

nf_conntrack           96976  5 ipt_MASQUERADE,nf_nat,nf_nat_ipv4,iptable_nat,nf_conntrack_ipv4

However, apt-file search nftables does not yield any results, nor does apt-cache search nftables.

So where can I get the new frontend for nftables, i.e. the nftables program matching the kernel modules?
