  TCP/IP version 2.0 for OS/2 can be installed on OS/2 Warp.  There are
  no known incompatibilities with OS/2 v. 3, and although this combination
  has not been fully tested, no problems have been observed.


>Does OS/2 LAN Client provide...

The formal announcement of OS/2 LAN Client hasn't occurred yet -- you'll
have to wait on this information.

As for compatibility and support for OS/2 2.1 users:

Web Explorer will be available via anonymous FTP on October 21.
It can be run on TCP/IP 2.0 and OS/2 2.1.

PPP support will also be available, roughly in the same time period.

Gopher is already available via anonymous FTP.  The version on
software.watson.ibm.com in /pub/os2/ews is the same as shipped in WARP.

It is possible to install the Warp Internet Connection kit on top of
TCP/IP 2.0, although this is not formally supported.  You must be running
OS/2 3.0, you must have the latest CSD for TCP/IP 2.0, and you
must install the Internet Connection kit after TCP/IP 2.0.  The
compatibility issues are:

(1) The Ultimail package in the Internet Connection kit is currently
configured only for Internet mail, and not for use on a LAN.

(2) While you are connected to the internet, your default route, domain, and
name server are all on the Internet.  If you are accessing LAN resident
TCP/IP resources simultaneously, this can create problems. You can
get around these problems in one of two ways:

(a) You can end your internet connection when you want to access TCP/IP
hosts on your local network, or

(b) You can add subnet and host routes for TCP/IP hosts you access through
your LAN gateway, and you can add entries in a hosts file for TCP/IP
hosts on your LAN, so that their names can be resolved.  Once this is
done, you can simultaneously access LAN TCP/IP hosts and Internet TCP/IP
hosts.  (You probably want to set ipgate off to disable routing through
your own machine.)

Knowledgeable users will figure this stuff out, but OS/2 version 3 will
be used by many less experienced folks.  For this reason, and because
this combination has not been formally tested, the
official position is that TCP/IP 2.0 and the Warp Internet Connection 
are incompatible -- which is not true.   The problems listed above
will be addressed for OS/2 LAN Client.

BTW, the Warp Internet Connection kit should not be installed on OS/2 2.1.  
Ultimail and IBM Dialer have some dependencies on OS/2 3.0.
