Remote access
Definition
A type of VPN that keeps data encrypted between two locations without needing credentials or client apps on devices using it.
Features
How It Works
Intended to connect entire networks, usually from different locations
They work by routing traffic between two site-to-site VPN tunnels.
It requires to launch the application (client), sign in, and keep it running for as long as want to use it.
It works by creating a “tunnel” between two networks.
The VPN uses gateways at each location, which encrypt all traffic that passes through.
All traffic (data) has to be encrypted at the gateway, which is solely responsible for protecting the data and sending it through the tunnel to the other side.

How It Works
enables users who are working remotely to securely access and use applications and data that reside in the corporate data center and headquarters, encrypting all traffic the users send and receive.
When an offsite employee sends data through a VPN, it is encrypted, so even if a hacker is able to intercept that data, they won’t be able to use it.
No client-side installation or maintenance should be required. ...
It is user-friendly. ...
It offers high levels of security.

How It Works
Updates of the network are exchanged periodically.
Updates (routing information) are always broadcast.
Full routing tables are sent in updates
one of a family of IP Routing protocols, and is an Interior Gateway Protocol (IGP) designed to distribute routing information within an Autonomous System (AS).

a process that enables one, unique IP address to represent an entire group of computers. In network address translation, a network device, often a router or NAT firewall, assigns a computer or computers inside a private network a public address.
RIP uses a distance vector algorithm to decide which path to put a packet on to get to its destination. Each RIP router maintains a routing table, which is a list of all the destinations the router knows how to reach. Each router broadcasts its entire routing table to its closest neighbors every 30 seconds.
When a packet traverse outside the local (inside) network, then NAT converts that local (private) IP address to a global (public) IP address. When a packet enters the local network, the global (public) IP address is converted to a local (private) IP address.
The network address translation feature of NAT secures the private network by hiding the

the Microsoft implementation of a Remote Authentication Dial-in User Service (RADIUS) server and proxy. It is the successor of Internet Authentication Service (IAS)
centralized authentication, authorization, and accounting for wireless, authenticating switch, remote access dial-up and virtual private network (VPN) connections.
Network policies are sets of conditions, constraints, and settings that allow you to designate who is authorized to connect to the network and the circumstances under which they can or cannot connect.
