How does the hardware-based VPN client work?
The hardware-based VPN client maintains the IPsec VPN (and GRE tunnel termination) to the concentrator, while allowing cleartext IP communications locally within the small home office or branch.
How is remote access to the screen provided by VNC?
Explanation: In macOS, remote access functionality is provided by the Screen Sharing feature, which is based on Virtual Network Computing (VNC). VNC is a freeware product that is similar in functionality to RDP and works over port 5900.

T/F: A packet-filtering firewall remembers information about the status of a network communication.
What is T/F in IP?
T/F: Internet Control Message Protocol (ICMP) is a method of IP address assignment that uses an alternate, public IP address to hide a system's real IP address.
Why use both software and hardware VPN?
In order to deliver both mobility and breadth of services to remote teleworkers, it is very common to see users deploy both software-based VPN clients and hardware-based VPN clients at the same time. Having the hardware-based VPN connectivity extends virtually all IP services available on the campus to relatively fixed remote locations. Software-based VPN communications allows users to extend communications in highly mobile scenarios. All of these services must be accommodated on the concentrator side of the VPN. For this reason, the variation in RAVPN topology is most commonly seen at the concentrator end of the design, which is what we will focus the remainder of this chapter's RAVPN discussion on.
What is a RAVPN client?
RAVPN clients typically come in two general flavors, hardware-based clients and software-based clients. Software-based VPN clients run locally on the user's remote workstation or laptop, and they are used to connect to a centrally managed VPN concentrator, typically located on the enterprise campus. The strength of software-based VPN clients is rooted in the mobility that they provide. When deployed on a user's laptop, a software-based VPN client can securely extend confidential communications from the campus to anywhere that a VPN client can access Layer 3 communications. Software-based VPN clients are therefore useful for tunneling data from centrally located campus resources to the end user. However, they do have limitations, and because of these limitations, the use of hardware-based VPN clients is merited in some situations. Specifically, software-based VPN clients terminate VPN connectivity locally on teleworkers' laptops and do not allow for the secure networking of other Layer 3 devices at the remote end of the VPN (such as a hardware-based IP Phone) over that VPN. Additionally, software-based clients will not support the termination of GRE locally, and therefore they will not typically support multicast data flows. Hardware-based clients, though inherently less mobile, address many of the functional limitations found in software-based IPsec VPN clients.
Why use VPN concentrator in a DMZ?
Due to the nature of IPsec and firewalls, the placement of the VPN concentrator in a DMZ design is critical to the success of the greater RAVPN architecture. Figures 3-7 through 3-10 outline several DMZ topologies that we will use to explore common design issues which must be addressed in RAVPN design. Each of these designs pertains to an IPsec VPN concentrator deployment for effective termination of client IPsec VPN tunnels in an RAVPN environment.
What are the two core elements of a RAVPN?
As we discussed in Chapter 1, "Introduction to VPN Technologies," the two core elements that comprise an RAVPN topology are VPN concentrators and VPN clients. These two elements communicate with one another over a predefined media at Layer 3 of the OSI Model. As such, these two entities can be connected over any media that will support Layer 3 between concentrator and client, including dial-up networks, Internet connections using DSL, and 802.11 wireless media. Because the underlying communications are relatively independent on the IPsec portion of the RAVPN, we will discuss clients and concentrators communicating with one another over a ubiquitous Internet connection, and will discuss RAVPN design in greater detail in Chapter 10, "Further Architectural Options for IPsec."
Where is a VPN located?
Hardware-based VPN clients are typically found in small, remote locations that do not have dedicated connectivity to a central hub IPsec router. These devices are commonly found at home offices that have DSL- or cable-modem connectivity to the Internet. The hardware-based VPN client maintains the IPsec VPN (and GRE tunnel termination) to the concentrator, while allowing cleartext IP communications locally within the small home office or branch. Therefore, hardware-based VPN components add a networked element to the SOHO (small office, home office) or small branch environment that allows users to extend voice, video, and data securely from the campus.
Why use software based VPN?
Software-based VPN clients are therefore useful for tunneling data from centrally located campus resources to the end user. However, they do have limitations, and because of these limitations, the use of hardware-based VPN clients is merited in some situations. Specifically, software-based VPN clients terminate VPN connectivity locally on ...
Is a VPN a secure IP?
As workforces become increasingly mobile in nature , this changes the dynamics of a secure IP network. Remote Access VPN deployments have become the central focus of secure connectivity in enterprise mobility, allowing secure Layer 3 communications to any VPN endpoint that has an internet connection to the appropriate VPN concentrator. We've discussed some of the business drivers for enterprise adoption of RAVPN deployments during our introduction to VPNs in Chapter 1. Now we will explore some common architectures for delivering RAVPN services to the enterprise.
