Doesnt have to be a remote IP...
If you can somehow even map a remote to some MAC address or incoming
virtual interface (such as a VLAN) that would do it as well.
Alternatively, you should probably look at namespaces  - i just find it
more usable when you have overlapping/conflicting ip addresses. You
of course will have to run strongswan per namespace if you dont want to
hack strongswan.

cheers,
