Hi!

I wrote the story below before I read PChuck's article "File
Sharing
On A
LAN With Two Routers" and now wonder whether or not to send this
message
as
File Sharing and Remote Connection are two tasks I still want to be
able
to
do after separating LAN into subnets, as well as maybe Print
Sharing.


I don't know if this is the correct forum for a question like this
and
please redirect me if you can.

I have a network operating between two houses that are about 900
Metres
apart. The setup is this:

PCs are all XP Pro.

(House1) PCs <--> Switch <--> AP (Point to Point) <--> Roof Antenna
((((( )))) (House2) Roof Antenna <--> AP (Point to Point)<-->
Switch
<-->
PCs and Internet(Router/Modem Combo). Currently all devices are the
one
LAN
(all addresses in the 192.168.0.x 255.255.255.0 subnet).

I was thinking that to keep the traffic off the APs (why? Just
because
and
to learn stuff) I could create two subnets at each house and place
a
Router/Switch (I have two spares Vigor 2104P and Dlink DI-524)
between
the
switch and the AP at each house. I was also hoping to use the DLink
Router
to limit the times that the kids could access the internet as they
would
have to go through the router to get to the internet on the other
subnet.

In order to test this theory I have setup the following at my
house:

PC1 <--> Router/Switch(DLink) <--> Router/Switch(Vigor) <-->
Switch
<-->
PC2-3 and Internet(Router/Modem Combo).

WAN Port on DLink Router connected to LAN Port1 on Vigor Router
PC1=192.168.3.2 255.255.255.0 gateway = 192.168.3.1
DLink Router LAN = 192.168.3.1 255.255.255.0 WAN = 192.168.0.137
(I
just
picked this ip randomly on the 2nd Subnet)

WAN Port on Vigor Router not yet connected
Vigor Router LAN = 192.168.0.1 255.255.255.0 WAN = not yet setup
PC2 = 192.168.0.11 255.255.255.0 Gateway=192.168.0.138
PC3 = 192.168.0.12 255.255.255.0 Gateway=192.168.0.138
Internet Router/Modem = 192.168.0.138

With this setup I can ping the 192.168.0.0 subnet from 192.168.3.0
subnet
but I can't access the internet(Can ping 192.168.0.138). I am
hoping
this
is
because I have not yet set up the return leg of that journey(ie WAN
port
on
vigor to Lan port on DLink).

I have searched on the internet for a lot of information on what I
am
trying
to do and what I have found tends to deal with routing a private
Lan
onto
the internet and not really about routing between private subnets.
I
may
have stumbled across sites that deal with what I am trying to do
but
maybe
it was at a level above my current understanding.

Anyway these are some of my question/s.

Q1. Am I on the right track with these ideas?
Q2. How do I connect the two routers together? eg. WAN to WAN port
with
crossover or WAN to LAN on both Routers
Q3. Should these routers do the job?
Q4. When I move to the original setup will I have to configure
Access
Points
on their own subnet?
Q5. Could this be done with less equipment?
Q6. I have heard the phrase 192.168.x.x addresses are private and
non
routable addresses. Does this mean that they should not be routed
or
that
they cannot be routed or is it another meaning all together?

Thanks in advance
Troy

Troy,

I see your problem, I think. On your main LAN, 192.168.0/24, the
default
gateway is 192.168.0.138. On your DLink LAN, 192.168.3/24, the
default
gateway
is 192.168.3.1. Now, you need to define a default gateway for the
DLink
to use,
on its WAN connection, to connect to the Internet.

Without a default gateway assigned to the DLink WAN, any Internet
traffic
from
PC1 goes to its default gateway 192.168.3.1, and to the DLink WAN,
and
onto the
main LAN. And there it stays. The DLink WAN has to have a default
gateway
defined, so the Internet traffic that it gets thru its LAN,
192.168.3.1,
will go
thru 192.168.0.138. For the DLink, as for the computers on the main
LAN,
the
default gateway will be 192.168.0.138.

Q1 / Q2. The routers are connected properly. When you get this
working,
you'll
be moving all of your computers to the DLink LAN, and they will all
be
able to
share files. Just set the default gateway for the DLink to
192.168.0.138.
Q3. These routers should do the job.
Q4. Why do you wish to move to the original setup?
Q5. I'm not sure what you're accomplishing with the Vigor setup as
a
switch,
and connected to another switch. Are the Vigor and the switch
located
in
the
same place, or are they separate?
Q6. The subnet 192.168.x.x is private (non-routable) so that it can
be
used on
any private (non-routed) LAN in the world, without fear of being
duplicated by
any public LAN anywhere in the world. You can only use 192.168.x.x
behind
a NAT
router. A NAT router handles the entire 192.168.x.x subnet
privately,
and
the
world sees only the WAN address. In your case, for instance, your
main
LAN sees
192.168.0.137, and that address is translated by the DLink into the
192.168.3.x
subnet.

Please let me know, at your earliest convenience, if these answers
are
understandable. It would be hella easier to setup your network,
then
to
explain
it.

Chuck

Thank you for your response. Just for your information some of my
responses
may be 24 hours apart as I go home and try suggestions from this
group. I
can't seem to find this newsgroup on my home computer for some reason.

Q1/Q2. The computers will remain as per the original setup but with
Routers
placed in between the switches and APs.(Re: Q4 APs on own Subnet)
Probably
remove switch at house1 though. House2 has Gigabit switch and NICs for
fast
file transfers at house2. The DLink already has the Gateway set to
192.168.0.138 but with no luck accessing the internet.

Q3. OK. Thanks.

Q4. See Q1/Q2.

Q5. House2 has Gigabit switch and NICs for fast file transfers at
house2.
The Switch and Router are separate in the test setup but would be
together
if I get this to work properly. In the current Test setup I have the
two
Routers and PC1 next to each other for ease of wiring them together.

Q6. What you have explained is basically as I remember NAT working
however I
did not know that NAT would only work with the 192.168.x.x addresses.
I
though it would just translate any address to and from the one WAN
exposed
address. I can't say that I completely understand the term
Non-Routable
but
I do think I understand how NAT works and the concept of how it limits
addresses used on the WAN. Would it more accurate to say that the
192.168.x.x subnet can't be used for Public Addresses rather then to
say
it
can only be used for Private Addresses?

What's most accurate is to say that it ISN'T used for public addresses.
It
COULD be used, but by agreement (RFC 1918), no network provider will
setup
a
routing for you. Since it isn't used publicly, it can be used
privately,
in
safety, by anyone.
http://www.faqs.org/rfcs/rfc1918.html

I have cabled the WAN port of the Vigor Router to a LAN Port of the
DLink
Router and set the Vigor WAN ip to 192.168.3.136 255.255.255.0 and no
Gateway. I can now ping all addresses on 192.168.0.x from 192.168.3.x
and
vice-versa however I still get no Ineternet access from the
192.168.3.x
subnet. Subnet 192.168.3.x PCs set with gateway 192.168.3.1 and Subnet
192.168.0.x PCs set with gateway 192.168.0.138.

Which router does PC1 connect to directly? The DLink or the Vigor?
Make
up
your mind please. You previously gave us:
PC1 <--> Router/Switch(DLink) <--> Router/Switch(Vigor) <-->
Switch
<-->
PC2-3 and Internet(Router/Modem Combo).
Then, which router - the DLink or the Vigor, connects to the Switch,
and
by its
LAN or WAN port?

192.168.3.1/255.255.255.0 WAN 192.168.0.2/255.255.255.0 Gtwy
192.168.0.138)

Vigor Router WAN Port Connected to DLink Router LAN Port1 (Vigor LAN
192.168.0.1/255.255.255.0 WAN 192.168.3.136/255.255.255.0 Gtwy <Blank>)

Vigor Router LAN2 Port Connected to Gigabit Switch Port1 (DLink DGS1005D)

PC2 Connected to Gigabit Switch Port2 (PC2 192.168.0.11/255.255.255.0
Gtwy
192.168.0.138)

PC3 Connected to Gigabit Switch Port3 (PC3 192.168.0.13/255.255.255.0
Gtwy
192.168.0.138)

Speedstream 4200 Router/Modem Connected to Gigabit Switch Port4
(Speedstream
192.168.0.130/255.255.255.0)

Regards
Troy

Troy,

Try taking the Vigor out of the picture. Connect the DLink WAN to the
DLink
DGS1005D.

Where is 192.168.0.138? Should that be 192.168.0.130?

Sorry, you are correct 192.168.0.130 should have been 192.168.0.138. It is
the Speedstream 4200 Modem/Router that gives internet access.

I think I did already try the setup without the vigor Router and still could
not access the internet from the 192.168.3.x subnet. I will confirm that is
the case over the weekend.

Thank you for your help so far.

Regards
Troy

OK, Troy. We'll take it one step at a time. Let us know what you find out, and
I'll look thru your analysis again a few times while I wait.
