I have a setup similar to what your describing - a small LAN connected
to the Internet via an ISDN Router.  The model I use is a Netgear
RT338.  It has built in NAT, firewall, auto redial if the line drops,
DHCP, port forwarding, etc.  If you get a static IP, using a router is
a great way to keep a persistant connection.  This allows you to forgo
setting up PPP.  All the dial up functions are handled by the router
and if the connection drops, it keeps redialing until the connection is
re-established (with ISDN, dialing and connecting only takes about 1-2
seconds).  This router acts very much like a DSL router in that you
plug one port into your ISDN jack and the other port is a 10/100
ethernet connection that you can connect to your hub/switch on your
LAN.
Hope this helps,
Peter
