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.

That's weird. Do you happen to use any bridge in this system? Does ebtables-save give you anything? Otherwise, it shouldn't be taking a role in there.

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.

where did you install fail2ban from? I don't believe its in the C7 base repository....
I only have EPEL as additional repository . It is installed from EPEL repo , but ebtables is in base repo .
