# [NAME](#NAME)

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

# [DESCRIPTION](#DESCRIPTION)

There is a set of tools to help the system administrator translate a given ruleset from [**iptables(8)**](/man/os/iptables/iptables.8), [**ip6tables(8)**](/man/os/iptables/ip6tables.8), [**ebtables(8)**](/man/os/iptables/ebtables.8) and [**arptables(8)**](/man/os/iptables/arptables.8) to [**nftables(8)**](/man/os/iptables/nftables.8).

The available commands are:

•

iptables-translate

•

iptables-restore-translate

•

ip6tables-translate

•

ip6tables-restore-translate

•

ebtables-translate

•

arptables-translate

# [USAGE](#USAGE)

They take as input the original [**iptables(8)**](/man/os/iptables/iptables.8)/[**ip6tables(8)**](/man/os/iptables/ip6tables.8)/[**ebtables(8)**](/man/os/iptables/ebtables.8)/[**arptables(8)**](/man/os/iptables/arptables.8) syntax and output the native [**nftables(8)**](/man/os/iptables/nftables.8) syntax.

The **iptables-restore-translate** tool reads a ruleset in the syntax produced by [**iptables-save(8)**](/man/os/iptables/iptables-save.8). Likewise, the **ip6tables-restore-translate** tool reads one produced by [**ip6tables-save(8)**](/man/os/iptables/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)**](/man/os/iptables/iptables.8), and **ip6tables-translate** reads a command like as if it was entered to [**ip6tables(8)**](/man/os/iptables/ip6tables.8).

# [EXAMPLES](#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

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;
	}
}
```

# [LIMITATIONS](#LIMITATIONS)

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)**](/man/os/iptables/arptables.8).
