инструмент перевода для перехода с iptables на nftables (translation tool to migrate from iptables to nftables)
Имя (Name)
iptables-translate — translation tool to migrate from iptables to
nftables
ip6tables-translate — translation tool to migrate from ip6tables
to nftables
Описание (Description)
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
Использование (Usage)
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).
Примеры (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]

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