The 4-Port VPN Router, model TW100-BRV214, manages up to 80 Virtual Private Network (VPN) tunnels. IPSec, L2TP, and PPTP VPN pass-through sessions are supported and a configurable firewall ensures the highest level of security.

L2TP/IPsec provides a logical transport mechanism on which to transmit PPP frames, tunneling, or encapsulation, so that the PPP frames can be sent across an IP network. L2TP/IPsec relies on the PPP connection process to perform user authentication and protocol configuration. Configure L2TP/IPSec Attributes for UMN L2TP Native VPN. Now we can define the attributes specific to the University's central VPN service. Navigate to Network and Sharing Center. > Control Panel > Network and Internet > Network and Sharing Center; Click Connect to a network. Configuring a Basic VPN for L2TP/IPsec in the WebUI. The combination of Layer-2 Tunneling Protocol and Internet Protocol Security (L2TP/IPsec) is a highly-secure technology that enables VPN connections across public networks such as the Internet. Our experience trying to use L2TP/IPSec on the Cisco RV340 has been a nightmare of frustration! It appear to mangle the PSK and thus never manages to establish the encrypted tunnel fully. It is difficult to debug and certainly is not a pleasure to configure because no combination of settings gets it to work.

Define the IP address pool that will be used by the VPN clients. set vpn l2tp remote-access client-ip-pool start 192.168.100.240 set vpn l2tp remote-access client-ip-pool stop 192.168.100.249

Define settings requested for remote access using SSL VPN and L2TP. These include protocols, server certificates, and IP addresses for clients. Network. Network objects let you enhance security and optimize performance for devices behind the firewall.

The following sections describe how to configure the preshared keys on both the L2TP client and the server. If you use a Windows Server 2003 operating system for both client and VPN-based server, complete the instructions in both of these sections so that the L2TP that uses a preshared key can work. (Layer 2 Tunneling Protocol) An IETF protocol that lets remote users access the corporate network. The PPP protocol encapsulates IP packets from the user's devices to the ISP, and L2TP extends L2TP traffic uses UDP protocol for both control and data packets. UDP port 1701 is used only for link establishment, further traffic is using any available UDP port (which may or may not be 1701). This means that L2TP can be used with most firewalls and routers (even with NAT) by enabling UDP traffic to be routed through the firewall or router.
