Dedicated Servers question about

Hello BHW brothers!
Is it impossible to access the VPS through a dedicated server?

No, it's not impossible, but it cannot be easy. The main reason why it can be difficult is that the VPS is isolated from the rest of the network. As a result, you'll need to use a particular tunneling protocol to connect to the VPS. You'll also need to ensure that your firewall is configured correctly to allow traffic from the VPS.
