The tunnel testing mechanism is the recommended keepalive mechanism for Check Point to Check Point VPN gateways because it is based on IPsec traffic and requires an IPsec established tunnel. It uses IPsec traffic patterns to minimize the number of messages required to confirm the availability of a peer. Dead Peer Detection does support 3rd party Security Gateways and supports permanent tunnels with interoperable devices based on IKEv1/IKEv2 DPD (IKEv1 DPD is based on RFC 3706). In addition to Tunnel Testing, Dead Peer Detection (DPD) is a different method to test if VPN tunnels are active. Permanent Tunnels are shut down by deselecting the configuration options to make them active and re-installing the policy. Once a Permanent Tunnel is no longer required, the tunnel can be shut down. Check Point tunnel testing protocol does not support 3rd party Security Gateways. Tunnel testing requires two Security Gateways, and uses UDP port 18234. Tunnel Testing for Permanent TunnelsĬheck Point uses a proprietary protocol to test if VPN tunnels are active, and supports any site-to-site VPN configuration. For more information on MEP see Multiple Entry Point VPNs. When a Permanent Tunnel is configured between Security Gateways in a MEP environment where RIM is enabled, the satellite Security Gateways see the center Security Gateways as "unified." As a result, the connection will not fail but will fail over to another center Security Gateway on a newly created permanent tunnel. In a Multiple Entry Point (MEP) environment, VPN tunnels that are active are rerouted from the predefined primary Security Gateway to the backup Security Gateway if the primary Security Gateway becomes unavailable. This feature allows configuring specific tunnels between specific Security Gateways as permanent. Can be specified for a single VPN tunnel.Use this option to configure specific Security Gateways to have permanent tunnels. Can be specified for a specific Security Gateway.This option sets every VPN tunnel in the community as permanent. Can be specified for an entire community.The configuration of Permanent Tunnels takes place on the community level and: As long as responses to the packets are received the VPN tunnel is considered "up." If no response is received within a given time period, the VPN tunnel is considered "down." Permanent Tunnels can only be established between Check Point Security Gateways. A VPN tunnel is monitored by periodically sending "tunnel test" packets. Since Permanent Tunnels are constantly monitored, if the VPN tunnel is down, then a log, alert, or user defined action, can be issued. Administrators can monitor the two sides of a VPN tunnel and identify problems without delay.Įach VPN tunnel in the community may be set to be a Permanent Tunnel. Permanent Tunnels are constantly kept active and as a result, make it easier to recognize malfunctions and connectivity problems. Therefore it is essential to make sure that the VPN tunnels are kept up and running. Permanent TunnelsĪs companies have become more dependent on VPNs for communication to other sites, uninterrupted connectivity has become more crucial than ever before. For details see Monitoring Tunnels in the R80.10 Logging and Monitoring Administration Guide. See the status of all VPN tunnels in SmartView Monitor. It also controls the number of VPN tunnels created between peer Security Gateways. VPN Tunnel Sharing - Provides greater interoperability and scalability between Security Gateways.Permanent Tunnels - Keeps VPN tunnels active to allow real-time monitoring capabilities.You can manage the types of tunnels and the number of tunnels with these features:
