Virtual Tunnel Interface (VTI) support for ASA VPN module. The ASA VPN module is enhanced with a new logical interface called Virtual Tunnel Interface (VTI), used to represent a VPN tunnel to a peer. This supports route based VPN with IPsec profiles attached to each end of the tunnel.

Jul 09, 2017 · Configure IPsec VPN between Juniper Netscreen Firewall (Route Based) LAN-to-LAN or Site-to-Site VPN. A VPN gateway is used when creating a VPN connection to your on-premises network. You can also use a VPN gateway to connect VNets. The steps in this article will create a VNet, a subnet, a gateway subnet, and a route-based VPN gateway (virtual network gateway). Once the gateway creation has completed, you can then create connections. Jan 29, 2020 · Juniper Networks offers a wide range of VPN configuration possibilities, such as Route Based VPN, Policy Based VPN, Dial-up VPN, and L2TP over IPSec. Start here if you are looking for assistance with configuring a VPN between your Juniper ScreenOS Firewall products or between a ScreenOS Firewall and another vendor's VPN device. A route-based VPN is a configuration in which an IPsec VPN tunnel created between two end points is referenced by a route that determines which traffic is sent through the tunnel based on a destination IP address. Understanding Route-Based IPsec VPNs In distinction to a Policy-based VPN, a Route-based VPN works on routed tunnel interfaces as the endpoints of the virtual network. All traffic passing through a tunnel interface is placed into the VPN. Route-Based VPN As the name implies a route-based VPN is a connection in which a routing table entry decides whether to route specific IP connections (based on its destination address) into a VPN tunnel or not. This routing statement is placed in the routing table of the firewall/router such as any other static/dynamic/connected routes.

Aug 17, 2011 · Route-based VPNs require the introduction of a separate dynamic routing protocol (or static routes) to distribute VPN routing information among peers. Overall, I think it's fair to say that route-based VPNs offer a much more robust and versatile VPN solution than the policy-based VPN configuration we examined in part one.

Jan 22, 2009 · Juniper : Netscreen Remote Dial-UP VPN with AD Radius Authentication and route based VPN / tunnel interface Published January 22, 2009 | By Corelan Team (corelanc0d3r) The following procedure explains how to set up a Juniper ScreenOS based firewall to accept Netscreen Remote Client VPN connections and authenticate users using Active Directory Mar 15, 2005 · FortiGate to Netscreen-204 IPSec VPN Interoperability 15 March 2005 01-280007-0147-20050315 5 This technical note demonstrates how to set up a policy based IPSec VPN tunnel between a FortiGate-800 Antivirus Firewall and a Juniper Networks Netscreen-204 appliance. In the configuration example, the two VPN peers use preshared keys to Most times I've seen this problem, it was due to encryption domain (proxy ID) mismatch. Because you're using a policy-based VPN on the Juniper side and not a route-based VPN, you're going to see the Juniper side try to set up IPSec SAs that match the policies. For example, if your Juniper policy looks like:

This looks like exactly what I was doing. I connected a Netscreen 50 with a Cisco 1841. I opened a TAC case and got a Cisco tech that use to install Netscreen boxes. The documentation wants you to setup a route based VPN, we were only able to get this to work with a policy based VPN on the Netscreen box. Here is a snip of my config that worked.
