Sharing dialup is no different from sharing DSL or Cable.  Box1 is
gateway of your internal network.  For 2 boxes only, you can use
crossover cable.

NAT and DHCP are two different thing.  NAT is for masquerading the Box2
as Box1 when connecting to Internet, so outside will only see one box,
ie. Box1.

Samba or NFS are the 2 things that comes mind.
