Earlier posted in OS/2 networking but no answer .. maybe here?

For the first time I'm contemplating a workstation on a substantial size OS2
PEERLAN local network which I wish to connect to the Internet individually but
not to introduce IP interface to the whole LAN.

This means, as best I see it, there need to be two NIC cards in this single
box. The box I propose this on is an Intel 915GAVL motherboard with the Intel
10/100 NIC chipset MCP2 latest everything. It works beautifully now by
swapping the TCP/IP LOCAL setup between LAN0 as either a DHCP connection when
connected physically to the supplied ADSL modem, or .. when reset to a fixed
address setup and plugged into the local LAN. Of course a reboot is required
for that methodology to work.

Now I want to use LAN interfaces, one on DCHP for the Internet. The other one
for only the PEERLAN connection. Or at least that is what I think should be done.

Per what I understand about OS/2 LAN work, only one NIC can have DHCP
addressing. And obviously the 'standard' 127.0.0.1 private address will
remain. I contemplate using the current Intel on motherboard chip for that
DHCP connection as LAN0. As far as I know, I should maintain both IBM's OS/2
NETBIOS and IBM TCP/IP protocols as normal for this chip operation.

Next to maintain a common interface hardware scenario, I choose to use a
Kingston KTC-120 PCI slot second NIC card. I already have one installed on the
to be tested box. The normal OS/2 driver for it works fine. But, as I think I
should do, in this case I only ought to use the IBMOS/2 NETBIOS on this NIC
interface, since it's only purpose is to connect to the local PEERLAN operation.

My question next is what should the settings in the TCP/IP configuration be
here for the ROUTE setup?

Also I know from what I have seen so far, that a discrete ROUTE setup ought to
go in the SETUP.CFG operation for MPTN which ties this to the expected LAN1
interface enable work for the KTC120 card.

Also, from memory long ago at this, for just fixed addressing, how goes this?
Can there be two different routers here, one for the ADSL operation; the other
for the local LAN? Even if only the interface to the IP side handles DHCP and
so on? How do we get around the conflict that if there are two routers, both
may be focused on 192.168.1.1 setup addresses? Or is this some kind of a maybe
more than dumbo switch game and not just a router? On which side of the fence?

Can someone coach me through this new learning curve?

I would put the WAN side NIC on TCP only and the LAN side on TCP and
Netbios. You never know when a quick FTP or Telnet will get you out of
a spot of bother. :-)

The two NICs will be on different networks so routing *ought* to sort
itself out. The default route will be from the WAN side. If there are
two routers, one WAN and one LAN, then you need them on different
subnets. 192.168.0.1 and 192.168.1.1 for example. If you need the LAN
side machines to see the 'net then you need "ipgate on" in setup.cmd.
