similar to: C7 and firewalld, ongoing

If I've missed someone's response, apologies. As I said, my converted rules seem fine, and I can run the script that issues a bunch of direct rules for the built-in FORWARD rule... but when I try firewall-cmd --reload, it tells me error, that FORWARD is a built-in. Now, today, what I've been looking at is to run iptables-save, and what I see is this (in part): -A FORWARD -m conntrack

Hi List, Are you really using firewalld and network-manager on Centos 7 production servers or old way disabling network manager and using pure iptables like on C6? -- Eero

If the conversion were simple enough to be easily automated, the new system is probably no more than just a syntactic difference away from the old, and thus does not provide any

Does someone have a link to a how-to-do-it with firewalld, not "disable firewalld and use iptables"? mark

The Linux firewall system is currently undergoing yet another deprecation and migration from iptables to nftables. firewalld should

I need to be able to temporarily cut off the source of network slowdowns. What I used to do: Router with 2 x NICs running slackware 14. Execute iptraf-ng, choose IP Network Monitor and sort by Byte Count. The sorted screen always seemed a bit confusing but I could usually pluck a couple of IP addresses with racing byte counts and cut all traffic to them using an iptables rule. Then if I wanted to

I went for C6 on a Samsung NC10 (1.6GHz Atom N270 1GB RAM), only because it refused to boot off the C7 ISO for some reason, and I didn't want to

Hi there, Wouldn't that be a better solution to create a custom xml file to put in /etc/firewalld and load that "ssh-custom" service instead ?

HI, me and firewalld won't have a good start, but I hope we'll be good friends. One of my hosts must rerote traffic from one to another host. It isn't a big problem. I've a host witch must do: 1) forwarding port 25 tcp to a second host Here I've a special mail-relay. My external.xml look like this one: <?xml version="1.0" encoding="utf-8"?>

No, I think the rules you created might have a better place in a custom xml file instead of being given to firewall cmd directly :) On Fri, 26 Apr 2019 at 23:01, Kimberlee Integer Model < kimee.i.model at gmail.com> wrote: > I'm not sure I follow, you just think the modified one should be called > "ssh-custom", or you think there shouldn't be a modified service file

HI all, 1st time contributor here. I was using the guide on securing SSH, and noticed that the firewall-cmd snippets for filtering by requests per time seem somewhat outdated. From what I can tell the given snippets, relay arguments directly down to iptables, and do not cover both IPv4 and v6. (and in fact when attempting to extend to v6 the firewall would fail to reload). I came up with an

Thibaut, I did a little more reading, and according to both firewalld.service(5) and firewalld.org the service XML files, can only handle source/destination/port, and cannot handle the actions to be performed. I will update where possible to use the service files, but log/accept limit will still need to be encoded in rich rules. -- Kimee On Mon, 2019-04-29 at 20:43 -0400, Kimberlee Integer Model
