.252 means 2 IPs only, so in this scenario you cannot put the Remote Office
on the same interface. You need to configure a Sub-Interface and give it
the second subnet for the remote office.
Subinterfaces are covered in the Config Guide - I believe also in the Command
Line Admin Guide and there may be an appnote on the web.
Alternatively you could redo the entire WAN setup and use a larger subnet
to include both sites - but I think the subinterface is better.
