1. I can not add a computer to the group, but connect to it, knowing its IP address in Radmin VPN?
2. If I added a computer to a group, then I can hide all other participants except the administrator’s computer, for example, or hide all participants so that no one else can connect to other group members if he does not know the IP address?
1. No, you have to add this PC to your Radmin VPN network before connecting.
2. The feature you have requested is not implemented yet so we have added your request to our wishlist.
