to setup a VPN concentrator. I did not find any specific thread on this topic (pfSense as a VPN concentrator), apart of something about connecting pfSense to already existing, commercial VPN Concentrators. Probably I was just unable to find the right thread, I apologise if this is the case.

A virtual private network (VPN) is a valuable security technique that's commonly used to protect data sent across insecure networks. In this video, you'll learn about VPN technologies, types of VPN implementations, and how IPsec protocols are used to protect your data at the packet level. << Previous Video: Firewalls Next: Network Intrusion Detection and […] VPN concentrators typically come in one of two architectures: SSL VPNs and IPSec VPNs. VPN concentrators are ideal when you require a single device to handle a large number of incoming VPN tunnels. VPN concentrator SSL vs IPsec encryption. For web-based applications, all the VPN concentrators utilize VPN encryption using either IPSec or SSL. The use of IPSec requires you to have a client software in order to connect the VPN tunnel. It has a high-security and encryption level and provides more configurable options. CONFIGURATION > VPN > IPSec VPN > VPN Connection > Policy Hub_HQ Concentrator 1 In the ZyWALL/USG, go to CONFIGURATION > VPN > IPSec VPN > Concentrator, add a VPN Concentrator rule. Select VPN tunnels to the same member group and click Save. Spoke_Branch_A. 1 Go to CONFIGURATION > VPN > IPSec VPN > VPN Gateway, select Enable. In most cases, IPSec VPN traffic does not pass through ISA Server 2000. However, Cisco Concentrator 3300, with the latest firmware updates, uses "transparent tunneling" that uses User Datagram Protocol (UDP) ports 500, 4500, and 10000 to communicate securely between VPN clients and concentrators. After tested policy based and route based IPSec vpn, this post will do a quick test FortiGate concentrator feature. The VPN concentrator collects hub-and-spoke tunnels into a group.The concentrator allows VPN traffic to pass from one tunnel to the other through the FortiGate unit. Cisco VPN 3030 Concentrator—The Cisco VPN 3030 Concentrator is a VPN platform designed for medium to large organizations with bandwidth requirements from full T1/E1 through T3/E3 (50 Mbps maximum performance) with support for up to 1,500 simultaneous IPSec sessions or 500 simultaneous clientless sessions.

IPSEC is more secure than SSL. However, users need to configure client software on their device to be able to connect to the VPN network. Many businesses use IPSEC as the protocol for their VPN concentrator network. IPSEC is best to access a VPN from a fixed location like your home or office.

A VPN Concentrator vs. a Site to Site VPN: It is important to keep in mind that a VPN Concentrator is typically used in those scenarios where there is a One to Many (1: N) set up. This simply means that many remote employees are logging into just one physical location, where the server resides at.

VPN Concentrator vs IPsec encryption VPN concentrators generally use either IPsec (Internet Protocol Security) or SSL (Secure Socket Layer) encryption protocols. The SSL VPN uses the TCP port 443, and because most browsers are also using SLL, this type of traffic matches the best with most networks. IPSEC is more secure than SSL. However, users need to configure client software on their device to be able to connect to the VPN network. Many businesses use IPSEC as the protocol for their VPN concentrator network. IPSEC is best to access a VPN from a fixed location like your home or office. Which VPN concentrator encryption to choose: IPSec or SSL? There are two major security protocols that VPN concentrators use in encrypting files: Internet protocol security (IPsec) Secure socket layer (SSL) Internet protocol security - Files encrypted with this security protocol require client software to gain access to the private network A concentrator configuration specifies which spokes to include in an IPsec hub-and-spoke configuration. Settings: Concentrator Name: Type a name for the concentrator. Available Tunnels: A list of defined IPsec VPN tunnels. Select a tunnel from the list and then select the right arrow. Members: A list of tunnels that are members of the
