Sure, but normally, either .1 or .2 of a /30 subnet (ie, your .241  
or .242) is the externally-connected router of your ISP.  A few of  
the better ISP's will support switching their devices from being a  
router to acting like a bridge, thus requiring you to provide a dual- 
homed machine yourself.

How else are you going to provide a default route except by using an  
IP which is reachable on that subnet...?
