Secure remote access has protected diverse users while access controls provide precise permissions
The user interface of OpenVPN Access Server is good but can be improved. I would prefer to see it become more intuitive. I use Twingate as an alternative, and in Twingate, you see resources, while in OpenVPN Access Server, those would be IP addresses. You get to see dashboards and access views of who can access a particular resource or subnet. You can see who can access what resources from the user view, but you can also see the reverse, which is which resource can be accessed by what users. That reverse view would be a nice addition to have in a dashboard. Additionally, access logs associated with that resource would be helpful, so it would be beneficial to have different views for the same content. Beyond the positive aspects, I would like to see improvements in OpenVPN Access Server. Twingate offers a different approach to the same problem by moving more towards resource-specific resources and fine-grained zero-trust access, as opposed to entire subnets and entire networks. I would prefer to see views on resources. In the same way that we can define subnets, perhaps we could have views that describe what this particular subnet does and what this particular resource does. Then we can assign those resources and subnets to individual users and groups. It is more about granularizing the resources that can be accessed rather than simply bundling them under subnets or a list of subnets, which is the current approach. Apart from that, I would like to see UI enhancements in OpenVPN Access Server in the future. Making it more modern would be beneficial.
