KB-000035717 - Sophos Firewall: Set a Site-to-Site IPsec VPN connection using a preshared key

When the article begins with "This article contains the steps to configure a site-to-site IPsec VPN connection using a preshared key as an authentication method for VPN peers.", one would expect the instructions to be complete.

However, without modifying the ACL (device access), the steps will not work.

Please include the necessary configuration options in the VPN section of device access.
