[IPTABLES-TRANSLATE(8)](https://www.chedong.com/phpMan.php/man/IPTABLES-TRANSLATE/8/markdown)                  System Manager's Manual                 [IPTABLES-TRANSLATE(8)](https://www.chedong.com/phpMan.php/man/IPTABLES-TRANSLATE/8/markdown)



## NAME
       iptables-translate — translation tool to migrate from iptables to nftables

       ip6tables-translate — translation tool to migrate from ip6tables to nftables

## DESCRIPTION
       There is a set of tools to help the system administrator translate a given ruleset from **ipta**‐‐
       [**bles(8)](https://www.chedong.com/phpMan.php/man/bles/8/markdown)** and [**ip6tables(8)](https://www.chedong.com/phpMan.php/man/ip6tables/8/markdown)** to [**nftables(8)](https://www.chedong.com/phpMan.php/man/nftables/8/markdown)**.

       The available commands are:


       • iptables-translate

       • iptables-restore-translate

       • ip6tables-translate

       • ip6tables-restore-translate


## USAGE
       They take as input the original [**iptables(8)](https://www.chedong.com/phpMan.php/man/iptables/8/markdown)**/[**ip6tables(8)](https://www.chedong.com/phpMan.php/man/ip6tables/8/markdown)** syntax and output the  native  **nfta**‐‐
       [**bles(8)](https://www.chedong.com/phpMan.php/man/bles/8/markdown)** syntax.

       The  **iptables-restore-translate**  tool  reads  a  ruleset  in the syntax produced by **iptables-**
       [**save(8)](https://www.chedong.com/phpMan.php/man/save/8/markdown)**. Likewise, the **ip6tables-restore-translate** tool  reads  one  produced  by  **ip6tables-**
       [**save(8)](https://www.chedong.com/phpMan.php/man/save/8/markdown)**.  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)](https://www.chedong.com/phpMan.php/man/iptables/8/markdown)**, and **ip6ta**‐‐
       **bles-translate** reads a command like as if it was entered to [**ip6tables(8)](https://www.chedong.com/phpMan.php/man/ip6tables/8/markdown)**.


## EXAMPLES
       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
       COMMIT
       # Completed on Sat Dec 24 14:26:40 2016

       root@machine:~# iptables-restore-translate -f save.txt
       # Translated by iptables-restore-translate v1.6.0 on Sat Dec 24 14:26:59 2016
       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
       table ip filter {
            chain INPUT {
                 type filter hook input priority 0; policy accept;
            }

            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;
            }
       }
