Azure currently does not support increasing the number of site-to-site VPN connections beyond the limit of 30 for a single gateway SKU. However, there are alternative solutions to address this limitation. One approach is to upgrade to a larger gateway SKU, which will not only increase the number of connections but also enhance the overall performance and capabilities of your gateway. If upgrading the SKU size is not a viable option, you can explore Azure Virtual WAN (VWAN) as an alternative. VWAN provides a scalable and flexible network architecture that can accommodate a higher number of connections while maintaining optimal performance. For more details on how to proceed with these options, please refer to the following resources.
