Define VPN tunnel settings for policy-based VPNs
The Tunnels tab in the Policy-Based VPN editing view allows you to define settings particular to individual tunnels or disable some tunnels altogether.
The topology of the policy-based VPN (defined on the Site-to-Site VPN tab) determines which tunnels are shown on the Tunnels tab. If you have set up connection forwarding between the gateways on the Site-to-Site VPN tab, the number of generated tunnels is reduced according to the relationships and the capabilities of the gateway that forwards the traffic. The forwarding relationships are shown under Forwarding Gateways.
There are two types of tunnels:
- The Gateway<->Gateway list shows connections between pairs of gateways.
- The Endpoint<->Endpoint list shows the individual connections that form the tunnels in the Gateway<->Gateway list. There can be several connections at this level for any Gateway pair if one or both of the Gateways have multiple endpoints (Multi-Link). If both Gateways have only one endpoint, there is only one tunnel also at this level for the Gateway pair.
If a VPN Gateway has a Multi-Link VPN configuration, you can select whether to use tunnels as backups or actively balance traffic between them. Multi-Link is specific to Forcepoint NGFW, and is not part of the IPsec standard. You might not be able to use Multi-Link with third-party gateways. Satisfactory results can be achieved if the third-party gateway allows ICMP probes, RTT ICMP probes, and supports DPD. You can disable redundant tunnels to the third-party gateway on the Tunnels tab if necessary.
This tab is also where you can view the link summary. The link summary is a summary of addresses and settings that have been configured for individual tunnels. You might want to check the link summary when there are complex setups involving external components (such as a VPN hub configuration).
Before editing a policy-based VPN that is used in active VPNs, we recommend making a backup of the Management Server.

Next steps
Add Access rules and possibly also NAT rules to direct outgoing traffic to the VPN and allow incoming traffic from the VPN.
