You will indeed a second subnet for this guest lan. And, unless you use ProxyArp, event the CTC to your router TCPIP woild be a -small- subnet on its own. If you have only one TPF guest in this VM, it would indeed be easier to have a second CTC: one couple of CTC devices to TCP/IP VM, another couple to TPF. And, if the other side of thses CTC connections enables ProxyArp, thuis VM and this TPF can appear to live on the same subnet as the outside world.
