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

Dear Members, Please tell me how can I fix this problem. Against allow imap on firewalld, I cannot access to the server.

Hi, https://fedoraproject.org/wiki/Changes/firewalld_default_to_nftables mentions a docker-firewalld where can I find that package or source code? thanks --- Lee

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

That was just one of the proposed solutions. It looks like the moby-engine packager went with Proposed fix 1, since it includes a:

As matter of interest, why would you want to run firewalld inside docker?

Hi, I'm currently fiddling with Docker Swarm on three sandbox servers running CentOS 7. Unfortunately I couldn't get even the most basic configuration running. After some experimenting and investigating, it turns out there's a problem with FirewallD. Here's what I did first on every single node. # firewall-cmd --permanent --add-service=docker-swarm # firewall-cmd --reload I

Dear Yalang, that did the trick. If I look in the NAT table of the bridge I can see the generated rules. Probably wouldn't have though about that ever. Thanks a lot!

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.

Hi Sam, You can find the rules by below command, and it looks as below: # ebtables -t nat --list Bridge table: nat Bridge chain: PREROUTING, entries: 2, policy: ACCEPT -j PREROUTING_direct -i vnet0 -j libvirt-I-vnet0 Bridge chain: OUTPUT, entries: 1, policy: ACCEPT -j OUTPUT_direct Bridge chain: POSTROUTING, entries: 2, policy: ACCEPT -j POSTROUTING_direct -o vnet0 -j libvirt-O-vnet0 Bridge

Hi all, I posted this question several days ago, but did not get any answer until now. Since I still have no clue about the source of this error message, I repost a description of the problem including some code: A student at our institute fitted an aov model, and got the following error message: > plot(p.aov) Hit <Return> to see next plot: Hit <Return> to see next plot:

I assumed this was a Centos 7 mailing list and I was looking for help with IPTABLEs.I have used mailing lists before.? Copying a file to an email address didn't have that type of output.? I apologize. First of all is this a Centos 7 Mailing list that I can ask for help or have I made a huge mistake?? IF so, should I just attach the file to the email. I apologize for the output, I had no idea.?

Thank you.? I apologize for sending something that could be read.? There are more examples in there that I had commented out. Anyway,? here is my working iptables-save.? If someone could review my output and let me know if I am missing anything and if the order of the rules are the most secure they could be. TIA.

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
