subnet

After connecting to a remote location via OpenVPN, I am trying to access a server on a network that exists on a subnet such as 10.0.1.0/24. However, the network I am trying to access this remote server from is on the same subnet: 10.0.1.0/24. I am unable to connect to my remote server via typing in its IP because of this conflict. I am unable to even access the public internet while connected to the VPN.

Does anyone know how to mitigate this issue? I have access to the OpenVPN Access Server.

We have a existing class-c network with IP address range 11.22.33.44/24 (just for example). My domain controller has been configured within this subnet.
