VPN Options for a Charitable Organisation
I work with a non-educational Charitable Organisation of around 100 clients (Windows 7) and a Server 2008 R2 domain behind 2 Draytek routers. My colleague (the IT Director) has asked me to investigate a VPN solution. Currently, we have a number of RDP connections set up with appropriate port forwarding in the routers so key personnel can access their desktops or other internal systems whilst working remotely. We used to make farily liberal use of LogMeIn until they tightened up and now we have a licence with 10 computers associated with it. We are considering upgrading to Server 2012 within the next 6 months.
Several years ago, a colleague showed me CMAK and the creation of a VPN in a lab situation. That might have been Server 2000 or 2003 but, as I was new to the field, I didn't really take much in about the process or what it all meant. I don't know if this is a viable option for us. Obviously, I don't want a detailed walk through of what to do and how to configure the VPNs but I would value suggestions about which direction to aim so I can do some research. I suppose the main requirements are:
2. Secure (I suppose VPN is, by it's very nature, secure but we don't want to inadvertently expose the internal network to accidental or intentional threats).
3. Easy to configure and maintain at both the server and client end.
4. I suspect that we might roll this out to 20 users initially but, as it becomes established, we'll face the inevitable "me too" so it will have to be easily expandable.
5. I have a little experience with Linux but we are, essentially, a "Windows shop".
6. I guess someone might suggest Smoothwall and that could be a steep learning curve!
Thanks in advance.
