DESCRIPTION:
How to Create a Site to Site VPN Policy using Certificates from the Command-line Interface (CLI)
RESOLUTION:
Feature/Application:
This KB article describes how to create a Site to Site VPN from the CLI between two SonicWall UTM appliances using certificates for authentication.
Procedure:
For the purpose of this article, we use the following scenario:
| Site A | Site B |
| NSA 5600 | NSA 4500 |
| X1 IP: 1.1.1.1 | X1 IP: 2.2.2.2 |
| X0 Subnet: 10.10.100.0/24 | X0 Subnet: 172.27.24.0/24 |
| Site A Configuration |
configure terminal | Enter configuration mode |
| address-object ipv4 NSA-4500 network 172.27.24.0 255.255.255.0 zone VPN | Create an address object of remote network |
vpn policy site-to-site NSA-4500
enable
gateway primary 2.2.2.2

- domain-name=FQDN in the format "DNS Name:" in the SubjAltName field of the certificate
