Study Notes
-
VPN (Virtual Private Network) is a voluntary, user-initiated connection method for securely accessing a network over the internet. It operates at the OSI model layers 2 to 7.
-
Two well-known VPN variants are PPTP (Point-to-Point Tunneling Protocol) and L2TP (Layer 2 Tunneling Protocol) over IPSec.
- PPTP and L2TP are based on the Point-to-Point Protocol (PPP), which supports user authentication, data compression, and encryption.
- L2TP adds extra security through the use of IPSec, offering packet-level encryption, dual authentication, and protection against intercepted packets during user-level authentication.
-
A VPN can be used as a gateway for remote access clients or for site-to-site connections between Remote Access Server (RAS) servers.
- RAS servers can be virtual or physical machines, and they support multiple VPN connections and user authentication methods.
-
Network Policy Server (NPS) plays a key role in managing VPN access.
- By default, NPS denies access for remote clients.
- NPS enforces policies for network access, authentication, authorization, client health, and more.
-
NPS and the Remote Access Server can facilitate various configurations.
- Policies consist of conditions, permissions, constraints, and settings.
- Group conditions and constraints can be used to provide access to specific groups.
-
Host Credential Authorization Protocol (HCAP) is a third-party access server communication protocol that can be used alongside NPS.
-
Connection properties can be configured for the VPN client, such as IP address, authentication type, and allowed EAP types.
-
VPN settings include basic encryption, strong encryption, and the option for no encryption. Different protocols, such as PPTP and L2TP, have varying encryption capabilities.
-
Server-to-client remote access solutions in Windows Server 2016 offer several benefits, including support for direct access, NAT64, DNS64, and high-availability.
-
Remote Access Services (RAS) in Windows Server 2016 support various authentication protocols, such as PPTP, PPP Authentication Protocols (MS-CHAP, MS-CHAPv2, EAP, and PEAP), and Microsoft Point-to-Point Encryption (MPPE).
-
Choosing the best authentication protocol depends on the requirements of your network. EAP is the most secure, while MS-CHAPv2 is the least secure but easier to implement.
-
PPTP and SSTP (Secure Socket Tunneling Protocol) are both VPN protocols, but they have different strengths and weaknesses.
-
IP addressing, certificate auto-enrollment, and network policies are essential configurations for VPN connections.
-
The RAS server, NPS server, and Certificate Authority (CA) can be virtual or physical machines or hosted on Azure.
-
RAS system authentication protocols include PPP Authentication Protocols (PPTP, MS-CHAP, MS-CHAPv2, EAP, and PEAP), and Microsoft Point-to-Point Encryption (MPPE).
-
EAP and PEAP Authentication Protocols offer additional security through the use of certificates and mutual authentication.
-
Choosing the best authentication protocol depends on the security requirements and compatibility of your network. EAP is the most secure, while MS-CHAPv2 is the least secure but easiest to implement.
-
VPN protocols, such as L2TP/IPSec, PPTP, and SSTP, offer different advantages and disadvantages when used within a 2016 network environment.
-
When choosing between VPN protocols, consider the advantages of L2TP/IPSec, such as per-packet data authenticity, data integrity, replay protection, and data confidentiality.
-
Ports can affect the VPN connection, so it's essential to understand the implications of various ports and configure them accordingly.
-
In a VPN scenario, consider IP-addressing, certificate auto-enrollment, configuring NPS, setting up the RAS server, and setting up the client.
-
To configure a VPN client, consider the use of PPTP and SSTP, and follow the steps for configuring the RRAS server.
