Site to Site VPNs

SonicWall VPN is based on the industry-standard IPsec VPN implementation. It provides a easy-to-setup, secure solution for connecting mobile users, telecommuters, remote offices and partners through the Internet. Mobile users, telecommuters, and other remote users with broadband (DSL or cable) or dial-up Internet access can securely and easily access your network resources with the SonicWall Global VPN Client and GroupVPN on your firewall. Remote office networks can securely connect to your network using site to site VPN connections that enable network-to-network VPN connections.

The maximum number of policies you can add depends on which SonicWall model you have. The larger models allow more connections.

Remote users must be explicitly granted access to network resources. Depending on how you define access, you can affect the ability of remote clients using GVC to connect to GroupVPN, but you can also affect remote users using NetExtender and SSL VPN Virtual Office bookmarks to access network resources. To allow GVC, NetExtender, or Virtual Office users to access a network resource, the network address objects or groups must be added to the allow list on the VPN Access window. To access this window, select the DEVICE | Users > Local Users & Groups > Local Users > Add User > VPN Access.

This section describes site to site policies, including GroupVPN. Other sections describe auto provisioning and Tunnel Interface policies for route-based VPN. For specific details on the setting for these kinds of policies, go to the following sections:
