Dear Members, Please tell me how can I fix this problem. Against allow imap on firewalld, I cannot access to the server. [root at speedex ~]# telnet 153.153.xxx.xxx 110 Trying 153.153.xxx.xxx... telnet: connect to address 153.153.xxx.xxx: No route to host After stopping forewalld I can access to the server.

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

it looks like it does work - it just takes a REAL long time to load with "many" entries in the file. iptables was never slow. firewalld seems inefficient. I was able to add the line - restart the firewall, (wait) - see my packets dropped - remove the line - restart the firewall (wait) and able to ping again. I thought this "Direct.xml" file would be the fastest way for

Hi! I have a server running CentOS 7.7 (1908) with all current patches installed. I think this server should be a quite standard installation with no specialities On this server I have fail2ban with an apache and openvpn configuration. I'm using firewalld to manage the firewall rules. Fail2an is configured to use firewalld: [root at server ~]# ll /etc/fail2ban/jail.d/ insgesamt 12

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.?

I'm trying to figure out how to use firewalld on CentOS 7 to block access to ssh (on a custom port to control log bloat) and smtp submission except for specific source addresses, using ipset. I haven't been able to figure out how to combine a port number or service name with an ipset, either as a blacklist of nets or a whitelist of addresses. It looks like ipset with type of

Hello, I have been using ipset to blacklist badbots. Works like a champ! The only problem is if I do a system reboot, I lose the ipset and the rule. I changed /etc/sysconfig/iptables.conf to: IPTABLES_SAVE_ON_RESTART="yes" IPTABLES_SAVE_ON_STOP="yes" And followed the instructions in: https://www.centos.org/forums/viewtopic.php?t=3853 The changes are still not saved.

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.?

Hello,? I hope that I can ask some questions on this mailing list about IPTables. I am more familiar with IPTABLES instead of FIREWALLD.? I disabled FIREWALLD and installed?iptables-services. I have put together a script that I found on the web on how to set up a good set of IPTABLES rules to keep my server as secure as possible. I have two NICs. ETH0 and ETH1. ETHO is the internet and ETH1 is my

I'm running Centos 7.8.2003, with firewalld. I was getting huge numbers of ssh attempts per day from a few specific ip blocks. The offenders are 45.0.0.0/24, 49.0.0.0/24, 51.0.0.0/24, 111.0.0.0/24 and 118.0.0.0/24, and they amounted to a multiple thousands of attempts per day. I installed and configured fail2ban, but still saw a lot of attempts in the logs, and the ipset created was
