Point-to-point protocol over Ethernet
The Point-to-Point Protocol over Ethernet is a network protocol for encapsulating PPP frames inside Ethernet frames. It appeared in 1999, in the context of the boom of DSL as the solution for tunneling packets over the DSL connection to the ISP's IP network, and from there to the rest of the Internet. A 2005 networking book noted that "Most DSL providers use PPPoE, which provides authentication, encr…

What is PPP protocol?
Point-to-Point Protocol (PPP) PPP is used to implement TCP/IP over point-to-point connections (for example, serial and parallel connections). It is most commonly used for remote connections to ISPs and LANs. PPP uses the Link Control Protocol (LCP) to communicate between PPP client and host. LCP tests the link between client and PPP host ...
How to use PPTP?
To use PPTP, you set up a PPP session between the client and server, typically over the Internet. Once the session is established, you create a second dial-up session that dials through the existing PPP session, using PPTP. The PPTP session tunnels through the existing PPP connection , creating a secure session.
How does PPTP work?
PPTP is both simple and secure. To use PPTP, you set up a PPP session between the client and server, typically over the Internet.
How to dial into a modem?

Remote Access Protocols and Services
Today, there are many ways to establish remote access into networks. Some of these include such things as virtual private networks (VPNs) or plain old modem dial-up access. Regardless of the technique used for remote access or the speed at which access is achieved, certain technologies need to be in place in order for the magic to happen.
Remote Access Service (RAS)
RAS is a remote access solution included with Windows Server products. RAS is a feature-rich, easy-to-configure, and easy-to-use method of configuring remote access.
What is the best way to make sure RDP is working?
The first and most effective recommendation is to make sure that both your local workstation and destination server are current on their Windows updates. There have been a considerable number of vulnerabilities discovered over the years in regard to RDP, and these have been addressed regularly through Windows updates.
What is RDS gateway?
Similar to the recommendation above regarding using SSL/TLS to secure the connection to a remote server, a Remote Desktop Services (RDS) gateway allows for a similar method to be used via a standard online portal. This provides a central access location that users can RDP from to a large number of target servers, as well as the use of remote apps. In addition to permitting access in a secure manner, this also allows for logging of legitimate users as well as potential brute-force attack attempts.
What is a VPN connection?
If you need more than just RDP access or require more than what just one RDS gateway will allow, then a Virtual Private Network (VPN) connection may be just what you require. These access methods are highly secure and allow for any supported device to communicate as if it were directly attached to your network.
What is the default port for RDP?
The default port for RDP traffic is TCP 3389, and anyone scanning the network deliberately for this port will be able to quickly find any number of servers listening. Changing this port to something less obvious would be tremendously helpful, but can take a considerable amount of time to initially set up.
Can you connect to a server remotely?
There are dozens of different ways to connect remotely to server s, but the recommended method for quite some time has been through the use of remote desktop connections. Unfortunately, while the use of the Remote Desktop Protocol (RDP) is relatively well protected over short distances, it can be vulnerable to attacks if left unsecured on the web. Worse, it’s become an even more lucrative target to exploit with the recent increases in working from home.
Is RDP secure?
In addition, we want to make sure that our RDP sessions are using secure protocols to communicate to and from the servers. This is because while the RDP channel itself is encrypted, it is possible in older versions of RDP to leverage a vulnerability in order to allow unauthorized access via a man-in-the-middle attack. Therefore it is strongly recommended wherever possible to secure your connections via SSL/TLS.
Is it safe to leave your network exposed?
While it is certainly possible to leave your systems directly exposed on the internet and RDP in directly with no security at all, this is a very bad idea. Fortunately there are two very well-used and secure methods that can help to not only keep your network more secure but to log who is attempting to breach it.
Why is POTS a popular remote access connection method?
POTS is a popular remote access connection method because few minor disadvantages are associated with it. The disadvantages are limited bandwidth, and thus a limited maximum data transfer rate, and the inferior analog signal when compared to digital methods, such as ISDN and DSL.
Why is remote access not part of my network?
Because a computer using remote access is not a part of your network, it will not use local area network (LAN) technologies to connect to the network. The remote computer will instead use other kinds of connection methods to connect to the LAN, including the following: Other digital connection methods (including one of the digital subscriber lines, ...
How many channels are there in an ISDN line?
An ISDN line has two types of channels. The data is carried on special Bearer channels, or B channels, each of which can carry 64Kbps of data. A BRI ISDN line has two B channels. One channel can be used for a voice call while the other is being used for data transmissions, and this occurs through time division multiplexing on one pair of copper wires. The second type of channel is also multiplexed onto the one copper pair, is used for call setup and link management, and is known as the signaling channel, or D channel (also referred to as the Delta channel ). This channel has only 16Kbps of bandwidth.
How to connect a cable modem to a computer?
If you are going to connect the cable modem via USB, simply install the software driver for the cable modem on the computer, and then plug in the cable modem. The computer will detect the modem and configure it automatically.
What are the advantages of ISDN?
These are the main advantages of ISDN: 1 It has a fast connection. 2 It offers higher bandwidth than POTS. BONDING yields 128Kbps bandwidth. 3 There is no conversion from digital to analog.
Why is ISDN used?
Because it is capable of much higher data rates at a fairly low cost, ISDN is becoming a viable remote user connection method, especially for those who work out of their homes. ISDN uses the same UTP wiring as POTS, but it can transmit data at much higher speeds. But that’s where the similarity ends. What makes ISDN different from a regular POTS line is how it uses the copper wiring. Instead of carrying an analog (voice) signal, it carries digital signals. This is the source of several differences.
How to connect Ethernet to modem?
If you are using Ethernet to connect, you must have an Ethernet NIC in your computer that is properly installed and configured. Then, once the NIC is installed, all you need to do is connect the cable modem to the NIC with an appropriate 10Base-T patch cable (RJ-45 connector on both ends, usually supplied with the cable modem). The thing to keep in mind is that the cable modem’s Ethernet connection is physically and electronically the same as a medium dependent interface-crossover (MDI-X) port on a hub or switch, meaning that you can connect your computer, which has a medium dependent interface (MDI) to the cable modem with a straight-though cable.
What is remote access VPN?
VPN: VPN, short for Virtual Private Network, is a private network formed using public Internet.
What is IPSEC protocol?

What is a VNC?
VNC (Virtual Network Computing): VNC is a technology for remote desktop sharing, a form of remote access on computer networks.
Types of Tunneling and Encryption
Tunneling involves using protocols to encapsulate or encrypt data packets so that will pass through the Internet in a secure fashion. Think of encapsulation and tunneling like peas in a pod. The peas are the data packets (unencrypted) and the pod encapsulates or encrypts the peas so they cannot be seen.
Remote Access
Here is a high level example (Figure 1) of how a remote host can connect to an internal corporate network which can be referred to when reviewing the types of remote access solutions: Remote Access Service (RAS), Point-to-Point over Ethernet (PPPoE), Remote Desktop Protocol (RDP), Independent Computing Architecture (ICA), and Secure Shell (SSH).
