Domains

A domain represents a site-to-site VPN connection. The VPN connection must use the IPsec protocol to establish a secure, encrypted tunnel over the internet. It is mandatory to use port 4500 (for IPSEC NAT-Traversal mode) and UDP protocol.

A site can be connected to a domain only if a gateway is assigned to it. To create a domain, at least two sites are required and each must contain a gateway. A domain supports up to eight remote sites connected to a single main site. In this configuration, all remote sites are connected directly to the main site in a star topology. Each remote site maintains a point-to-point connection with the main site, and there are no direct connections between remote sites. The remote site can also be referred to as the Connected Site.

Once a domain is created, the main site cannot be converted to a remote site or vice versa. To make such changes, you must delete the existing domain and create a new one.

The Domains tab displays the list of domains configured.

The details of the domains in the Domains page are listed under the following categories:
