 The VPN gateway provides a connection point on the Scaleway side of a Site-to-Site VPN tunnel. It has the following properties, which you can customize when you create the gateway:
 
 - **Region**: The geographical location in which the gateway is created. It must be in the same region as the other Site-to-Site VPN resources (customer gateways, routing policies, connections) that you want to use it with.
-- **Name** and (optioanlly) **tags**: A name and tags to identify the gateway.
+- **Name** and (optionally) **tags**: A name and tags to identify the gateway.
 - **Gateway type**: Different gateway types are available for different prices. Pricing is based on **bandwidth**, and the **maximum number of connections** the gateway can be used for.
 - **Private Network**: Each gateway must be attached to a single Scaleway Private Network. The network chosen cannot be modified after creation of the gateway. The gateway will get both an IPv4 and IPv6 address on the Private Network. Other Private Networks in the VPC will be able to learn the route through the VPN gateway.
-- **Public IP address(es)**: The address(s) used to establish the VPN tunnel. Maximum of one IPv4 /32 and one IPv6 /128 address per gateway. Gateways with both types of IP will be able to support dual tunnels for a single connection, one IPv4 and one IPv6, providing increased redundancy.
