I found the same thing to be true.  We investigated remote connection using the
internet and the first advice we received was: 1) at each location install NT
server. 2) at each location do frame relay to a local ISP 3) pay extra for 
IP address.

Upon further investigation: 1) NT is not needed, just a router. 2) a direct 
relay through the local phone company from remote direct to head quarters was 
LESS per month than the ISP was going to charge us (install cost was same) 3)
the router (or any old 486 in the closet using LINUX.....the fastest TCP/IP
implementation going!) can act as a proxy server.

IMHO each device in the flow is a potential weak link.  I guess this is a case
where less is more. :)

You might want to check out Netopia router or Red Hat/Caldora LINUX distribution
for remote access via TCP/IP.

Around here we have USWest providing unlimited (2 channel) ISDN ($208 for 3com
ISDN modem) for $63/mo and NW Nexus will give us a static IP/ISDN connection for
$95/mo using a Netopia router ($700 from NW Nexus/ $125 setup), domain name and 
email address' (each additional $5/mo).....NT didn't show up anywhere on the 
of requirements.

AKAIK, NT might be needed if you wanted to do SNA over TCP/IP.  Haven't gotten
that deep yet.  My standard recommendation has been to plug your AS/400 ethernet
card into your hub, connect router, and if you must, use a firewall product for
LINUX to protect your network.  It's one of probably a gazillion working
solutions, but I get a personal satisfaction of keeping Micro$oft out of the
loop. :)
