How about? http://www.firewalld.org/documentation? ?-> firewall.direct(5) https://twoerner.fedorapeople.org/firewalld/doc/firewalld.direct.html priority="priority" The priority is used to order rules. Priority 0 means add rule on top of the chain, with a higher priority the rule will be added further down. Rules with the same priority are on the same level and the order of these

Is there any way to order rich rules in firewalld? If I remove all rules and add them back in firewalld seems to put them in whatever order it feels like. Alternatively, how can I change the default policy of a firewalld zone? At the moment I don't see any way to have a zone accept traffic by default other than adding a rich rule allowing 0.0.0.0/0. -- Jeff White HPC Systems Engineer

Hi, again, folks, I'm trying to convert a number of iptables rules to firewalld rich rules. I need to do this, because this is, in fact, a firewall, to protect access to servers with sensitive data. It will limit access to the servers behind it to a specific network, and nobody else, and allow only certain services through. What I've been trying to find is a script/program that

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

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

Dear members, Please tell me what's wrong. After setig firewalld, I got fail on cloud-init with reboot. The server is rebooted, but I cannot access from internet. Before reboot I can access form internet. And before setig firewalld, there's no problem on reboot. /var/log/cloud-init.log shows following Jul 17 14:18:46 biz105 cloud-init: ci-info: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!Route info

HI, here I have an eMail with connected to a DMZ 10.0.0.0/24 network. This server holds 10.0.0.87 There are two firewall-hosts one with CentOS 6 10.0.0.10 and one with CentOS 7 10.0.0.17 The CentOS 6 has the following iptables-rule (extract): ----------------------8<----------------------8<----------------------8< *nat -A POSTROUTING -o eth1 -j MASQUERADE -A PREROUTING -i eth1 -d

Hi Everyone, I'm trying to get squid + wccp on a Centos 7 box working with a Cisco router. I've done this before several times using Centos 6 and iptables, but never on Centos 7 with firewalld. I've searched far and wide for clear, concise instructions on how to do what I want in Centos 7. I've pieced together what I've found to come up with what I thought should work.

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

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"?>

On CentOS 7 with firewalld I have a box with numerous interfaces acting as a NAT gateway. This works but I noticed that it routes/forwards traffic not just from my internal zone to external zone but also between interfaces within the internal zone. How can I prevent that traffic? I've tried adding direct and rich rules to deny the traffic but it doesn't work. Direct: firewall-cmd
