Thanks to all who posted replies. As my cousin is not "into" computers, 
the solution must be automatic, and transparent to her. A bridge won't 
do because I can't administer it remotely. So - it appears that the 
solution is one that utilizes the DNS addresses obtained by the dhcp 
client on the external interface. I think I've got enough to get me 
started.

My $80 D-Link wireless router handles these DNS server updates
transparently; I'd guess most of the products in this category do.

Finally - speaking of remote administration - I'll also need some way to
get updates when the address of the Soekris changes. I think some
variation on "dynamic dns" services might be the way to go here - any
other ideas?

V/r,
