Fantastic product, been using for months and very happy, keep up the good work.
Question: We have a virtualized Zeroshell running on Server 2008 R2. All works fine, except VPN throughput is very slow – Host to Lan using OpenVPN and PPTP. Tried switching everything off to the bare minimum, so basic port blocking on the firewall and no layer 7 stuff.
Getting around 5-8Mb download, but oddly the Upload can shoot to 18-20Mb. Is there any known reason for this?
Server is in a tier 1 DC, with anywhere up to 50Mb symetrical so shouldn’t be the connectivity.
Running latest version of Zeroshell with Radius authentication and out the box settings.
