Is there a way to view VPN connections (in the past) on Windows Server 2011 SBS?

I have looked in the Event Viewer, but I can't seem to find them!

You can view current VPN connections in RRAS, but to view them after the fact you need to enable detailed auditing and within the configuration, you can configure the systems and successful and/or failed events you wish to audit. Following articles outline how to enable and analyze the results:
http://support.microsoft.com/kb/814595/
http://www.windowsecurity.com/articles/Understanding_Windows_Logging.html
http://207.46.19.60/technet/prodtechnol/windows2000serv/maintain/monitor/logevnts.mspx

However, using auditing can be time consuming to filter and extract.

Another option is to add the lines below to each users logon and log off script to create a log file. It would give you UserName, ComputerName, date and time, in a simple single line, followed by the IP from which they connected, if needed. If you wish to know logoff times as well, you can add the same lines to a log off script in group policy (if you don't already have one: User Configuration | Windows settings | Scripts | Logoff). You likely won’t need the last line (IP address) in the log off script.

As written below it will create the log/text file in \\Server\Logs\LogOns.Log and the entries will look like:
