We have iptables-compat-restore, this uses the nf_tables netlink frontend and packet classification code, plus x_tables extensions to run iptables code. It should allow us to schedule the x_tables core for removal at some point. In Montpellier, we mentioned that distro could add a iptables-restore symlink to iptables-compat-restore so it becomes visible that we're relying on the compat infrastructure. This iptables-compat-restore interacts with nft via translate layer, so if you just 'nft list ruleset' after using iptables-compat-restore, you will get a translation (if available). -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
