To make a connection, at least one system must have a VPN server, more commonly called a VPN concentrator, that's designed to accept remote connections from either a single system (for remote access) or another VPN concentrator (for site-to-site).

Layer 2 Tunneling Protocol (L2TP)

Although it does not allow you to use LAN resources. 

The Split Tunnel method allows you to have a secure connection while also using LAN resources as well. 

Generic Routing Encapsulation is the tunnel being created when the user is involved with the PPTP.]]> 2020-12-31 13:55:38 UTC https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047658521 https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047658570 1. Split tunneling in reference to VPNs is when you use the vpn to encrypt some of your traffic, but also allowing to not go through the VPN and just access the internet. 

2. Site to Site VPNs are usually used by bigger corporations so they can link together at different locations or sites. ]]> 2020-12-31 13:55:45 UTC https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047658570 https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047658871 There are VPNs that can use TLS and other VPNs can use IPSEC.

VPNs can let you connect a single single system to an existing LAN (remote access) or you can connect 2 complete LANs  (site to site).]]> 2020-12-31 13:56:28 UTC https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047658871 https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047659020 Site to site VPN generally do not disconnect and are considered "Always on".

Before you could only  connect to the VPN and nothing else, so that meant if your computer was connected to a VPN and opened a Web browser, your computer went through the VPN connection and then went back out and used the Internet connection on your LAN. This is called a Full tunnel. 

Current VPN technologies enable you to configure a VPN connection to send only LAN traffic through the tunnel. All other traffic ignores the tunnel. This is a split tunnel and is the most common type of tunnel.

Basically, the protocol creates a secure “tunnel” between the client and the server, and all the data and traffic that passes through that tunnel is encrypted.]]> 2020-12-31 13:57:17 UTC https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047659220 https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047659703 A VPN disguises your IP address when you use the internet making its location  invisible to everyone.

SSTP works by establishing a secure connection between a VPN Client and a VPN server.

a PPTP transports all your online data and traffic, securing it with its encryption at the same time.]]> 2020-12-31 13:58:23 UTC https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047659703 https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047659895 ESP or Encapsulating Security Payload, can provide protection for the IP packet. but ESP doesn't have to be used due to the fact it encrypts the IP header, this can cause problems with the router for it because it can't read the header.
An AH (Authentication Header) protocol can provide authentication and integrity. This can be used on entire IP packets that include the header and the data payload.]]> 2020-12-31 13:58:51 UTC https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047659895 https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047660201 -  site-to-site VPN is when you want to connect two sites to each other across the public internet, but you want to send all of the data between those sites in an encrypted form. 
-  Host-to-host VPNs, and they’re usually all software-based. ]]> 2020-12-31 13:59:35 UTC https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047660201 https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047660562 With VPN split tunneling you can reduce to total traffic load of a vpn.

A site-to-site VPN provides a more secure connection for corporate networks to communicate with its remote offices through a single network.

VPN concentrators insert the local traffic in internet packets and sends them through the tunnel. ]]> 2020-12-31 14:00:50 UTC https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047660768 https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047660882 SSTP is a secure socket tunneling protocol that uses a VPN to PPP traffic

SSTP operates using TCP and uses port number 443]]> 2020-12-31 14:01:07 UTC https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047660882 https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047660891 SSTP vs PPTP vs L2TP

SSTP: uses secure socket layer (port 443) tunneling which creates the most secure connection  between the server and the client. May be able to connect where other protocols cannot due to use of port 443

PPTP used  encryption to create a good connection using TCP but it was not quite as secure as SSTP. It is, however, very compatible with a very wide range of systems

L2TP uses network layer 2 (as the name implies) for the VPN connection. It can also be used by many Operating Systems, but runs the chance of being blocked by firewalls.]]> 2020-12-31 14:01:08 UTC https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047660891 https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047661187 A successful VPN connection gives your remote system an IP address on your LAN 

VPNs have gotten widely popular due to there ability to move confidential data securely over a wide open network ]]> 2020-12-31 14:01:40 UTC https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047661187 https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047661224 VPN (Virtual Private Network)-this will allow your IP address location to not be visible to anyone. 

Split Tunneling-This specific method is used with LAN, while doing so it gives you the user a secure connection.]]> 2020-12-31 14:01:46 UTC https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047661224 https://padlet.com/jgilchrest1/mbdpo09asu7yspqe/wish/1047661286 Full Tunnel is more secure and is better if you are connecting to a network you do not trust. 
Split Tunnels is less secure but it might be necessary if you  need access to local  resources.

Internet connection is used on the LAN. 
Split tunnel- divides up ethernet traffic between traffic going to and from. It allows the VPN a smaller ethernet connection.

It is also better to use full tunnel if you are connecting from a network you do not trust, like any local area. 
Split tunnel may be necessary if you need to access both local resources and OSU resources at the same time, but it is less secure. 
L2TP-good tunneling protocol but does not encrypt data

Full tunnel is the traditional way in which user creates an encrypted tunnel, but does not have access to the LANs resources.

• PPTP -  use 128-bit key (least secure)
