Hello @Darío Soler , Thank you for reaching out. I think the requirement can be satisfied by having Multi-Site-to-Site VPN connection using Azure VPN Gateway. In Azure each virtual network can have only one VPN gateway but you can create multiple sit-to-site tunnels to the same VPN Gateway based on the SKU used and when you create multiple connections to the same VPN gateway, all VPN tunnels share the available gateway bandwidth. For additional information you can go through this document regarding Multi-Site VPN.
Please let me know if this not the correct solution for you I will be glad to continue with our discussion.
