An option to edit running VPN servers as pending changes where the VPN server is automatically restarted when 0 users is online on the server, so it is possible to change “any” setting which is then applied when no user is using the specific VPN server.
This would be difficult to change due to the current design. There are some server options that can be changed while the server is running including the replica count and some client specific options. I have made changes to the repository to allow these changes on running servers. This will be included in the next release.
