OpenVPN Support Forum

Hi all,

I installed OpenVPN with Markontech's script and it works like a charm ( https://markontech.com/linux/install-op ... ian-10-11/)

On Debian I had no issues. However, I need this to run on the same server on which I have FreePbx running, so I installed it on the FreePbx distro, CentOS. It works perfectly until I restart. Once I reboot the server, I can still connect to the VPN but there is no incoming traffic. I checked the status and there are no errors. If I remove and reinstall it works again. Please help me out how can I get more info so I can fix the issue.

Thanks in advance for your help.

That is exactly what is happening to me as well. You will notice that on the FreePBX openVPN will stop working after about a day. On CentOS 7 x64, it only takes a reboot and BAM... No more internet traffic even though we can connect.

I imagine this is CentOS that is doing something on a reboot.

If you haven't fixed it yourself by now...
After a new install and openvpn up and running:
Check what related services arr running. will show them.
Also check the status of the services: Also dump the firewall settings to a file Now reboot and repeat the above commands and check for differences.

I had a similar problem when iptables-openvpn.service was started before the network was up.
The clue to that was in comparing the output from iptables-save before / after the reboot.
