[SOLVED]new firewall rules in debian 9 ?

[stephane78]

Before debian 9 was released I had read that there is a new firewall command instead of iptable but I didn't remember this command and I didn't found it anywhere in the documentation.does someone knows something about it? or the name of this command to do a "man"?

IPtables works just fine. I don't know one way or the other about a replacement. An alternative is the firewall in your router/modem; set it as tight as you can live with.

ok thank you Bulkley.

I use nftables:

It has several advantages over iptables, most important of which (for me) is the declarative syntax, similar to OpenBSD's pf firewall, which makes it *much* easier to use.
