Yes, stick the IPs in on each end.  If an IP changes, so what?  I am assuming
you are using freeswan w/ key authentication...
The person that has the IP you are trying to connect to will not have the key
if it is the incorrect box.  AFA which should connect first, have them both
contact each other.  DNS would probably be your best bet though...
