It should work.

Note that openswan picks a name for the phase1 part, which might change
upon getting further into the negotiation. So it can "switch" the
connection to the right one.

If this is a linux-linux tunnel, the easy solution is to use raw RSA
with leftid=@somestring and rightid=@otherstring. That should nail the connection
down properly in phase 1 to only that one tunnel connection.
