I am trying to set up a 2012 Server for VPN access, this is not a domain, just a plain 2012 to store files for local access but now I would like to install VPN so we could access the files from remote sites.
I have read and followed many guides, all seem straight forward, but I am keep getting random error such as 678,79z, 801, 807 (I am guessing each time I change the client settings the error reflect the changes).
The router in use is just a normal TP-Link with PPTP support which I am told when it is selected it should automatically setup GRE47 together eith 1723.
The clients I have tried are Win7 Pro, XPx64 but so far without any sucess.
I then tried this on another 2012 that is hosted with BT Fibre and their latest Business Hub, again setting up PPTP but then get error 678. According to BT, it does allow PPTP/GRE47 once the PPTP port forwarded but I just can't seen to get anywhere.
After all the equipment tried, I am narrowing down to human error, but what am I doing wrong ? would be really grateful for any help on this one.
