Making my DS411+ use a VPN service

[nasking]

Hi all,

Apologies if this is the wrong subforum, but it seemed to fit.

I have a DS411+ that I very much like and that has performed well over the last 4-5 months that I have owned it.

However, I recently signed up for a VPN service for added privacy/security, and was wondering how I would go about making the NAS use this new service. I can connect either through L2TP or PPTP, but I am not sure where I would plug in the credentials to the NAS setup to get it connected. I have tried inputting both my L2TP and PPTP settings into the "Tunnel" tab of the network settings page, but that didnt work. Is there a package I can download that would allow me to do this?

Thanks!
