About iptables to nftables Converter

Convert iptables and ip6tables commands, or a whole iptables-save file, into nftables syntax in your browser. The output matches what iptables-translate and iptables-restore-translate 1.8.11 print, so you can plan a migration without installing anything. Rules nft cannot express stay as comments, and the places where iptables-translate prints nft that fails to load are corrected or flagged.

Key Features

Converts single iptables or ip6tables commands and complete iptables-save files
Matches iptables-translate 1.8.11 output, checked against the real tool on more than 25,000 rules
Labels every rule as translated, translated with a warning, kept as a comment, or an error
Corrects 1.8.11 output that nft rejects or places wrongly, such as IPv4 set types in IPv6 rules and off-by-one insert positions
Reads Docker, UFW, fail2ban, kube-proxy and WireGuard rule sets
Runs entirely in your browser, so your firewall rules never leave your machine

Move an Ubuntu 24.04 or Debian 12 server from iptables rules to a native nftables ruleset
Convert /etc/sysconfig/iptables on RHEL, Rocky Linux or AlmaLinux before switching to nft

Why are some rules left as comments?

iptables-translate only converts what nftables can express directly. Matches such as u32, recent, string and physdev, and targets such as CHECKSUM and NETMAP, have no translation in iptables 1.8.11, so the rule is printed as a comment with its original options. Rewrite those by hand: recent limits usually become a meter or a dynamic set with a timeout, and a u32 header test usually becomes a payload expression such as ip hdrlength. A few rules this converter could translate are withheld instead, because iptables-translate 1.8.11 prints a rule that would match different traffic, and each one carries a warning that says why.
