[ale] Can I tell my Linksys router to always serve the same I P address?

I noticed the same behavior here, but I didn't know if I could rely on 
it or not.  The manual for this version of the box is quite useless for 
doing anything other than installing it.  It doesn't address most of the 
options available.  I haven't seen a way to set the expiration time 
anywhere either.

I've got a spare system or two.  I may have to turn one of them into a 
router.

Thanks,
Jim.
