# Can I run multiple OpenVPN tunnels on a single machine? Yes, of course. If you are running 2 or more OpenVPN instances on the same machine, you will need a separate virtual TUN/TAP adapter and a separate port (using the **port** directive) for each instance. Make sure each TUN/TAP adapter has a unique, non-overlapping subnet using **server**, **server-bridge**, or **ifconfig**.
