Links allow creating site-to-site links with IPsec using Pritunl Link clients. The Pritunl Link client communicates with the Pritunl cluster using HTTPS this allows linking sites without needing to provide database access. Multiple link clients can be deployed to each site for automatic failover. Automatic routing table support is available on AWS, Google Cloud and Ubiquiti Unifi. The diagram below shows the infrastructure design of Pritunl IPsec links.
