Demon conflicts with intranets?

Not sure if this is the right place for this query, but it is to do with
W95 and IP. I'll cross-post it to d.i.s.win95 and demon.ip.developers. 

I want to know if there is a way to run an IP intranet on my local
machines, without messing up my Demon connection. When I added IP
networking to my LAN, Turnpike could no longer find the news and mail
servers at Demon when I logged in. 

The root problem is that, unlike many other ISPs, Demon assigns a
permanent IP address to each user, and this conflicts with the IP
address which my machine uses on the local intranet. 

I use two other ISPs on this machine. They both use dynamically assigned
IP addresses, and have no problems. I don't intuitively see why a
dynamic IP address should conflict less than a static one (they would
both be in danger of seeing two IP addresses on this box) but there you
are... 

Demon support is emphatic about this. They say I can't do it. I should
either 
1. use NetBEUI or IPX on the LAN, or 
2. Only connect from a standalone box (a dedicated Demon box, with no
file transfer to my other machines? not an option really)

Or of course, the one they didn't mention: 

3. Stop using Demon. 

It seems to me that there must be another option. Indeed, given that
every W95 and NT user has IP available, and the intranet is currently
the hottest topic in corporate networking, for Demon's sake there had
*better* be another answer. There are going to be thousands of people
trying this - I got the impression from Support that this is a regular
and irritating call for them. 

Obviously, I can reset my intranet so that my PC has the same IP address
on the intranet as on Demon. The problem then is that I have to renumber
the other machines - can I do this without conflicting with other Demon
subscribers when online? 

The preferred intranet addresses are the 'official' internet addresses
reserved for intranet use:  192.168.0.0, and up from that, 192.168.0.1
etc. With a subnet mask of 255.255.255.0

This conflicts with a Demon dial-up, so I put my own ip number a.b.c.d
(can't remember it off-hand) on my machine. I can then use the same
subnet mask, and use addresses a.b.c.d+1 on the other machines. 

However, chances are Demon already uses these numbers for other
subscribers. It's no problem while I'm not connected to Demon, the
intranet runs happily, but am I right in thinking that if I logged in
while the intranet is up, there could be a conflict, with the legitimate
users of those addresses? 

I don't intend to try this blind - I'll take the intranet down before I
log in again. 

But if that set-up causes a problem, is there a combination of IP
numbers and/or subnet masks I can safely use on my intranet which would
allow me to use my own Demon number on the intranet?

yes

set the DNS servers centrally not in the DUN connection. The central
values override the specific ones (a Microsoft cock-up IMHO).

to fix that use "server assigned" on the DUN connection

>Demon support is emphatic about this. They say I can't do it.

depends rather what you asked :(

sounds like that is set wrong - you'll need to check the settings in the
properties pages for the TCP/IP bound to the Ethernet card.

This is not really d.i.developers material. You should be asking in
demon.ip.support.win95 or one of the planetwide Win95 groups.

Yes, but ONLY in d.i.developers.  You did NOT cross-post; you MAY have
multi-posted (sending the same message as separate articles to two or
more newsgroups is NOT cross-posting, and unnecessarily wastes
bandwidth).  Multi-posted articles, apart from wasting bandwidth, also
have the effect of fragmenting discussion, because readers of one group
do not see responses in the other group(s), unless they happen to read
those as well.

Find out how to cross-post, and DO SO (but only when appropriate).

(A cross-posted article saves bandwidth, because although it appears in
all the newsgroups to which it's posted, only one copy of the message
travels across the 'net, between news peers, or between server and
clients.)

I don't believe this.  I can't help with configuration, but I very much
doubt this is the problem.

No.  *Interfaces* have IP addresses, not computers.  Your lan and modem
*must* have different addresses.  You have to make sure that the modem
is the default route for unrecognised addresses (i.e. for all the
Internet except your local intranet).

Definitely so.

Ah - I see what you mean. Yes - I need to know about that. Do replies
also get cross-posted? Only if the person replying wants them to (and
thinks about it, I guess). 

And yet, another useful response from the original post.

Traditionally, yes, since it's considered bad netiquette to shift the
thread into a single group when it was oriignally in many WITHOUT SAYING
SO.  The responsible posters of cross-posted articles will arrange in
advance for the thread to continue in ONE relevant group (through use of
the Followup-To header); unless the original post so says, it's rather
rude to split it off by posting to only one group instead, since this
leads to fragmentation of the discussion.

Forte (Free) Agent is a major culprit here: because their original
software was totally ignorant of the concept of cross-posting, it failed
to deal properly with cross-posted material, and presented it multiple
times to the readers (jst as if multiposted).  So a tradition grew up to
post only into the group being read.  It's *always* wise to look at the
Newsgroups line to find out just whereabouts responses are appearing: I
note that this is *only* in demon.ip.developers, but originally the
thread was more widely cross-posted, so I'd guess that someone else had
earlier restricted distribution.

IMO, having done the sort of thing you're talking about I would
say Turnpike blows chunks. It annoyingly almost works in a number
of ways. I wouldn't recommend it, although as a disclaimer I have tried
hard, but not yet *really* hard.. Its treatment of Winsock is vile.
  I use a linux configured as a gateway (see my recent post in demon.ip.
support.unix) and the whole LAN has access thru it. Web,ftp,news
documents are all cached for the whole LAN too, as well as providing
seamless (to all clients and applications) autodialling access to the net.
Click on a URL from anywhere on the LAN and 15s later you have it.
Unless its centrally cached of course :)

Yes, and you should be thankful for it. Dynamic IPs are an utter curse.

Hmm, maybe not with the s/ware they provide..

Or even trying some other s/ware. FWIW, I'd be interested in hearing
opinions on this: http://www.wingate.net/ http://www.mdaemon.com/
and http://www.ndaemon.com/ which provide mail, news and gatewaying
on a Windows system. It looks pretty good (although pricey for a large
userbase) but linux has the edge (altho' is admittedly a winner is the
BOSFH set-up stakes).

There is, and I'm surprised Demon haven't looked into it especially as
so many people apparently ask about this.

In essence you actually have two addresses, 192.168.1.1 and 158.152.x.y
since you have two interfaces (ie devices connecting you to a net). Try the
WinGate stuff as I think currently this is about the only way to do it with
a
play-play OS.

FWIW, to be safe avoid 192.168.0.1 since you'll need a broadcast addr
of 192.168.0.255 and some things see .0. as a broadcast address. IME,
it worked here (I changed to .1.255 recently) but unless anyone knows
better, I'd avoid it. I've seen both used in documentation with no real
explanation as to why - the broadcast addr is All My Own Work and
prob'ly wrong.

The replied to article is quite old, and this question was answered in
d.i.developers some time ago. It is possible to approach this in a
number of ways depending on the exact requirements.

if you have questions of this kind, then demon.ip.support.turnpike would
probably be the best newsgroup to use
