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
There is a set of tools to help the system administrator translate a
given ruleset from iptables(8) and ip6tables(8) to nftables(8).
The available commands are:
· iptables-translate
· iptables-restore-translate
· ip6tables-translate
· ip6tables-restore-translate
They take as input the original iptables(8)/ip6tables(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

}
chain OUTPUT {

}
}
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 are no translations available for ebtables(8) and arptables(8).
