Create IPSec Tunnel or a WireGuard Peer
After creating a VPN Gateway, you can create a Tunnel or a Peer based on your chosen VPN Gateway protocol.
To create tunnels or peers, follow these steps:
1. In the DCD, go to Menu > Network Services > VPN Gateway.
2. On the VPN Gateways page, click Create Tunnels or Create Peers based on the chosen VPN Gateway protocol.
3. Enter the following details:

Network CIDRs
Enter the following details:
Cloud Network CIDRs: Specify up to 20 IPv4 or IPv6 network addresses, separated by commas, on IONOS CLOUD that can connect to the tunnel.
Peer Network CIDRs: Specify up to to 20 IPv4 or IPv6 addresses, separated by commas, on the peer side that can connect to the tunnel.
Enter the following details in the Create WireGuard peer page:
Properties
Peer Name: Enter a peer name.
Description: (Optional). Enter a description.
Endpoint Configuration (optional)
You can specify the following optional details to enable the peer to use the specified IP address to connect with its remote peer. The peer connects via any available IP address when you do not specify the IP address.
Endpoint host: Enter a public IPv4 address or an FQDN.
Endpoint port: Enter a port number or you can also use the up or down arrows to choose a port number from the list. The port number indicates the UDP port on which a WireGuard interface will listen for incoming encrypted VPN packets.
Peers Configuration
Specify the following details to establish a secure connection.
Allowed IPs: Specify up to 20 IPv4 or IPv6 network addresses, separated by commas from which the traffic must be allowed to reach the respective peer. Traffic from all IP addresses are sent to the peer if you do not specify the network addresses.
Public Key: Remember to specify a public key for a secure transmission. The key is used to validate the sender and encrypt the data.
4. Click Save to save the configuration.
