For those following at home: it's quite possible that my problem was
due to a misconfiguration of the VMs' MAC addresses; in any case, the
pressing need for something functional (even if less secure) led us to
give up on StrongSwan for now. I'm sorry about that, but now I know
that StrongSwan is not actually that scary, I'm likely to try again at
some time in the future.
Thanks for the advice!
