Server closes after about 8 minutes

Mantaraya

I'm trying to install openvpn for the first time.
The device I'm using is a Netgear Stora Nas.
My devices starts but seems to be disconnecting after about 8 minutes.
I've tried both tcp and udp.
Last two days of my openvpn.log are:

Any help appreciated

Thanks in advanced.

I've discoverd that the daemon is shutting down after about 8 minutes.
If I start openvpn server.conf than it stays up.
In the 8 minutes prior to shutting down I am able to connect to my server.

I've tackled the problem.
It was an other process on my NAS wich was kiling my OPVN process.
If place a line in the rc.local and now it is working fine.

Which program was it? Just in case someone else runs into this down the road.

I have a Netgear Stora NAS.
The program which shuts my OpenVPN down is de Access Patrol. In case you need to get rid of the program helpful howtos can be found on the OpenStora forum at: www.openstora.com

Hi I also own the netgear stora and have the exact same problem.

Its unclear to me as to what you entered into your rc.local to overcome the problem, does this method mean you do not have to disable the access patrol as described in the Stora Wiki.

Hoping someone can help a linux&openvpn newbie.

Thanks

[update]
I'm hoping the following additions to rc.local have fixed the problem

/sbin/service openvpn stop
/usr/sbin/openvpn /etc/openvpn/server.conf
