fvdw-15 and OpenVPN

[spidercat]

Hi,

i'm trying to use openVPN included in this release.
i have already created certificates.
Using simple server / client configuration file, grant me access but i'm not able to "ping" anything.
Is there any special configuration "like ethernet bridge" that needs to be done before using OpenVPN with this hardware ?
Is there someone that use OpenVPN instaed of PPTP (the one visible from Web Interface)

Thanks a lot
