service openvpn start [FAILED] when using non standard port

acik

I have one old PC used as a firewall and OpenVPN server.
I bought a new one, installed Centos 5.8 and the last OpenVPN.

I copied OpenVPN files.
If I start openvpn manually, all works fine ! (VPN works)

If i try to start the service with "service openvpn start" i see [FAILED]

I tryed some things... When I change the configuration file to use the standard 1194 port, the "service" command starts perfectly OpenVPN !
(but I must to use different port)

Actually I solved by adding a launch script in rc.local....
