IPTABLES-TRANSLATE(8) System Manager's Manual IPTABLES-TRANSLATE(8)
iptables-translate — translation tool to migrate from iptables to
nftables
ip6tables-translate — translation tool to migrate from ip6tables
to nftables
ebtables-translate — translation tool to migrate from ebtables to
nftables
arptables-translate — translation tool to migrate from arptables
to nftables
There is a set of tools to help the system administrator
translate a given ruleset from iptables(8), ip6tables(8),
ebtables(8) and arptables(8) to nftables(8).
The available commands are:
• iptables-translate
• iptables-restore-translate
• ip6tables-translate
• ip6tables-restore-translate
• ebtables-translate
• arptables-translate
They take as input the original
iptables(8)/ip6tables(8)/ebtables(8)/arptables(8) syntax and
output the native nftables(8) syntax.
The iptables-restore-translate tool reads a ruleset in the syntax
produced by iptables-save(8). Likewise, the ip6tables-restore-
translate tool reads one produced by ip6tables-save(8). No
ruleset modifications occur, these tools are text converters
only.
The iptables-translate reads a command line as if it was entered
to iptables(8), and ip6tables-translate reads a command like as
if it was entered to ip6tables(8).
Basic operation examples.
Single command translation:
root@machine:~# iptables-translate -A INPUT -p tcp --dport 22 -m conntrack --ctstate NEW -j ACCEPT
nft add rule ip filter INPUT tcp dport 22 ct state new counter accept
root@machine:~# ip6tables-translate -A FORWARD -i eth0 -o eth3 -p udp -m multiport --dports 111,222 -j ACCEPT
nft add rule ip6 filter FORWARD iifname eth0 oifname eth3 meta l4proto udp udp dport { 111,222} counter accept
Whole ruleset translation:
root@machine:~# iptables-save > save.txt
root@machine:~# cat save.txt
# Generated by iptables-save v1.6.0 on Sat Dec 24 14:26:40 2016
*filter
:INPUT ACCEPT [5166:1752111]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [5058:628693]
-A FORWARD -p tcp -m tcp --dport 22 -m conntrack --ctstate NEW -j ACCEPT

add table ip filter
add chain ip filter INPUT { type filter hook input priority 0; }
add chain ip filter FORWARD { type filter hook forward priority 0; }
add chain ip filter OUTPUT { type filter hook output priority 0; }
add rule ip filter FORWARD tcp dport 22 ct state new counter accept
root@machine:~# iptables-restore-translate -f save.txt > ruleset.nft
root@machine:~# nft -f ruleset.nft
root@machine:~# nft list ruleset

}
chain FORWARD {
type filter hook forward priority 0; policy accept;
tcp dport ssh ct state new counter packets 0 bytes 0 accept
}
chain OUTPUT {
type filter hook output priority 0; policy accept;
}
}
Some (few) extensions may be not supported (or fully-supported)
for whatever reason (for example, they were considered obsolete,
or we didn't have the time to work on them).
There is no translation available for arptables(8).
