Sometimes, this does become a problem as the server can loop, starting
and stopping regularly. Luckily, there is a fix for the error 812 VPN
server 2012 issues. Below is a way to solve the RAS VPN server error
812.
How to solve error VPN error 812
If you’re concerned with the error 812 VPN
connection problem, here’s a fix. It involves a change to the primary
DNS. You will need to change this to the Domain Controller. @$#f$234
After you have achieved this, you will need to set up the secondary DNS
and make this the External Server. We need to go back to the Primary DNS
at this point and set this to 8.8.8.8 as this is Primary Google.
Once the settings have been applied, you can then check the VPN
connection. This should fix the problem, as it is a RAS server
connection issue. This solution does fix the VPN error 812 Windows 7,
Windows 8 and Windows 10.
These are just some of the issues that can affect you when you are using
a VPN. These issues tend to affect Windows users with some issues more
prevalent in some operating systems than others.
As a general rule all of the Microsoft systems can be affected by one or
other of these errors. Windows 7, 8, 8.1, 10, XP and Vista can all be
affected, but the solutions listed above should get you through these
issues. For further error code issues, check out the rest of our site.
Hopefully, all this information will help you along to a happy and stress-free VPN service experience, maintaining your anonymous and secure Internet surfing.

What is a VPN gateway and why should I have one?
A virtual private network
(VPN) gateway is a device that securely connects two or more computers,
computer systems, or other VPNs together over long distances. This
allows a private connection to be secured and encrypted against hackers.
The gateway creates networks that can be worldwide in scope. @$#f$234
A VPN is a cost-effective alternative for a corporation in need of a
private network between two remote locations. This is because a VPN uses
the internet to carry data between end points. The corporation only
needs to own or rent third-party gateway hardware at each end of the
link.
In addition to business use, personal VPNs are becoming more popular as a
means of protecting personal data such as banking transactions,
passwords, emails, or other legal matters from thieves and hackers. The
VPN gateway provides a proxy IP address, encrypts and decrypts
information, allows a person to mask their true location and also access
blocked websites.
A VPN gateway is an essential component of the VPN. It can be a server,
router, firewall or another device with networking and data transmission
functions. However, it is usually a router, installed at both the core
and remote sites. Gateways filter VPN traffic, blocking some traffic
while allowing other traffic, and routing the information through the
internet to the end destination.
They do these tasks using routing and tunneling protocols, IP address
assignment, name resolution, verifying legitimate users,
encrypting/decrypting and encapsulating the data to provide security
against prying eyes. They also perform integrity checks on the data,
ensuring no data is lost in transit. Gateways are also aware of the
network paths between the endpoints and can dynamically change the route
a data packet takes if some portion of the internet is unavailable.
VPN service providers offer free or paid VPNs. Paid VPNs are the preferred option as they offer more services than the free VPN providers.
VPN devices
VPNs operate at level 3 of the OSI model, which means the device is
between the actual physical transmission medium (copper or fiber optic
cables) layer and the layer that organizes the data for transmission.
The VPN device will take the data, analyze it and determine what actions
to take with the data. Routers are usually the preferred device, but
some level 3 switches, firewalls or other specialized devices, such as
hardware VPNs, can perform the same functions.
VPN security
VPNs use dedicated connections and encryption
protocols to secure the data they transmit. In addition to IPSec and
L2TP mentioned above, there are others such as Secure Sockets Layer
(SSL), Transport Layer Security (TLS) and Secure Shell (SSH). Using
these connections and protocols means that even if a hacker got some
private information, they would still be unable to read the data due to
the encryption.
IPSec operates in two modes: Transport mode,
encrypting the message, or Tunneling mode, which encrypts the entire
packet. L2TP generates a tunnel, and along with IPSec encrypting the
data, creates a highly secure VPN. SSL and TLS operate by using a
“handshake” between the two systems to create a secure connection. SSH
creates both the tunnel and the encryption of the data.
