[strongSwan] Does StrongSwan create tunnel devices, or only bind to an existing one?

I have the following setup:

[ subnet 1 ] --- [ gateway1 ] === [ gateway 2] --- [ subnet 2 ]

with subnet 1 being and subnet 2 being

Assuming I have no inside-facing interfaces on gateway 1 or 2 on the or network, respectively.  Will bringing up StrongSwan create tunnel devices for my subnet devices to use as gateway?

I am not seeing any on my gateways, but want to make sure that's the expected behavior.
