Configuring a star topology

Example of a scenario:

A company with its head office in Paris has two branches in Bordeaux and Madrid. The Accounting sub-network at the head office needs to exchange information with the Accounting sub-networks in the branches. The company's three sites are protected by SN firewalls managed by the SMC server.

The company has just acquired a new organization that also has an Accounting department and whose network is protected by a firewall from another vendor.

The administrator needs to know the address range of this firewall, which will be declared as an external peer, and the address range of the sub-network.

The chosen authentication method is by pre-shared key (PSK).

To configure VPN tunnels between the four sites, follow the steps below.
