This section describes how to monitor VPN tunnels.

VPN Tunnels Solution

VPN Tunnels are secure links between gateways. These Tunnels ensure secure connections between gateways of an organization and remote access clients.

When Tunnels are created and put to use, you can keep track of their normal function, so that possible malfunctions and connectivity problems can be accessed and solved as soon as possible.

To ensure this security level, SmartView Monitor constantly monitor and analyze the status of an organization's Tunnels to recognize malfunctions and connectivity problems. With the use of Tunnel views, you can generate fully detailed reports that include information about the Tunnels that fulfill the specific Tunnel views conditions. With this information you can monitor Tunnel status, the Community with which a Tunnel is associated, the gateways, to which the Tunnel is connected, and so on.

These are the Tunnel types:

A Regular tunnel refers to the ability to send encrypted data between two peers. The Regular tunnel is considered up if both peers have Phase 1 and Phase 2 keys.
Permanent tunnels are constantly kept active. As a result, it is easier to recognize malfunctions and connectivity problems. With Permanent tunnels administrators can monitor the two sides of a VPN tunnel and identify problems without delay.

Permanent tunnels are constantly monitored. Therefore, each VPN tunnel in the community can be set as a Permanent tunnel. A log, alert or user defined action can be issued when the VPN tunnel is down.

The configuration of Permanent tunnels takes place on the community level and:
- Can be specified for an entire community. This option sets every VPN tunnel in the community as permanent.
- Can be specified for a specific Security Gateway Dedicated Check Point server that runs Check Point software to inspect traffic and enforce Security Policies for connected network resources.. Use this option to configure specific Security Gateways to have Permanent tunnels.
- Can be specified for a single VPN tunnel. This feature allows you to configure specific tunnels between specific Security Gateways as permanent.

This table shows the possible Tunnel states and their significance to a Permanent or Regular Tunnel.

State	Permanent Tunnel	Regular Tunnel
Up	The tunnel works and the data can flow with no problems.	IDE SA (Phase 1) and IPSEC SA (Phase 2) exist with a peer gateway.
Destroyed	The tunnel is destroyed.	The tunnel is destroyed.
Up Phase1	Irrelevant	Tunnel initialization is in process and Phase 1 is complete (that is, IKE SA exists with cookies), but there is no Phase 2.
Down	There is a tunnel failure. You cannot send and receive data to or from a remote peer.	Irrelevant.
Up Init	The tunnel is initialized.	Irrelevant.
Gateway not Responding	The Security Gateway is not responding.	The Security Gateway is not responding.

VPN Tunnel View Updates

If a Tunnel is deleted from SmartConsole Check Point GUI application used to manage a Check Point environment - configure Security Policies, configure devices, monitor products and events, install updates, and so on., the Tunnel Results View shows the deleted Tunnel for an hour after it was deleted.

If a community is edited, the Results View shows removed tunnels for an hour after they were removed from the community.

When a Tunnel view runs the results show in the SmartView Monitor client.
