Hello , I have recently downloaded and setup Centos 7 1503 on a device and encountered a remote connection problem which I was only able to solve via removing ebtables package . After setup , I wanted go forward with IPtables instead of Firewalld , so remove firewalld and install iptables. After configuration and tests , I installed Fail2Ban ,(which brought ebtables with it ) and after reboot I was not able to connect to the device. After every reboot, I had to logon to the device locally , restarted iptables service and then I was able to connect remotely. I traced my steps backwards and figured ebtables was the problem. After removing it , I could connect remotely after reboots. IPtables service is running just fine. I want to use fail2ban , but I need to solve ebtables problem first. So, where sould I start? I couldn't locate ebtables logs . Thanks in advance.

Otherwise, it shouldn't be taking a role in there. Marcelo
Hello , No I do not use bridging . It is a fresh install , with no alterations . I only removed NetworkManager and manually configured the network script for static IP . After " yum install fail2ban" (which brought ebtables with it) and reboot , I cannot connect . Kind regards. 2015-04-12 6:12 GMT+03:00 Marcelo Ricardo Leitner <marcelo.leitner at gmail.com>:> Hi, > > > On 11-04-2015 06:00, Mehmet Allar wrote: > >> Hello , >> >> I have recently downloaded and setup Centos 7 1503 on a device and >> encountered a remote connection problem which I was only able to solve via >> removing ebtables package . >> >> After setup , I wanted go forward with IPtables instead of Firewalld , so >> remove firewalld and install iptables.

I don't believe its in the C7 base repository.... -- john r pierce, recycling bits in santa cruz
I only have EPEL as additional repository . It is installed from EPEL repo , but ebtables is in base repo . 2015-04-14 22:43 GMT+03:00 John R Pierce <pierce at hogranch.com>:> On 4/11/2015 2:00 AM, Mehmet Allar wrote: > >> After setup , I wanted go forward with IPtables instead of Firewalld , so >> remove firewalld and install iptables.
