IP Config with 2 NICs Wizard dont work, Static dont work!

Post by jd » Mon, 16 Jan 2006 06:01:26


ell here I am, 3rd time lucky and alls well with internal and external.
Theres still a view weirdness going on like during setup not auto logging in
and then upon completion it did auto login once! bizarre.

Interestingly I note the internal adapter preffered DNS is a loopback
127.0.0.1 as I would have expected.

Whether my company will migrate to SBS is yet to be seen. I have to say that
all my experiences with MS Server03 and SBS are suggesting its just to
risky!

My first attempt at running SBS was ruined when I uninstalled AD, clearly
SBS simply cant cope with any manipulation. As when I reinstalled AD it all
went belly up.

So I have a test: Ive aquired a full SBS license which should arrive from MS
soon and new fast PC (yes it takes 5 hours to install SBS - 3 of which is
AD!) and if I cant migrate my settings on this trial SBS to the new SBS,
then its going in the BIN!

Off now to if open relay is default like the other MS mailserver offerings
;)

Sorry, how do I get the text out of c:? for the ipconfig?

latters!

IP Config with 2 NICs Wizard dont work, Static dont work!

Post by jd » Mon, 16 Jan 2006 22:17:15

One NIC Is WAN the other is LAN

But SBS refuses to configure them with the wizard claim's network setup
error

Ive tried manual static IPs to no avail.

My setup is simple, I have a dedicated ADSL Ethernet modem with IP of
192.168.1.10
and a LAN router of 192.168.1.20

Both have DHCP disabled.

The SBS was clean, no errors, the only addition was the 2nd NIC.

Is there anyway to bypass SBS wizards? It seems from experimentation that
directly administering the NICs does not update the various WAN/LAN
application interfaces.... ie I can't browse the Web.

Why is the Internet Connection wizard in Server Management reporting a
Network Setup err in any event???

Are their logs for these wizards? Ive looked in the usual
systemmanagement/logs but cant see anything likely.

Look at the diagrams at: (the text is mostly for SBS 2000)
http://www.yqcomputer.com/

Does this describe your setup?
Can you please post an ipconfig /all for the server?

I don't understand "dedicated ADSL Ethernet modem with IP of 192.168.1.10
and a LAN router of 192.168.1.20". Normally (at least in the US), the ADSL
modem plugs into a router's WAN port and then the external NIC on the SBS
plugs into a port on the router. The ADSL modem IP address would be a
public address rather than a private one.

What make/modem of ADSL modem and router do you have?

thanks for quick post! Ive been at this 48hrs

Yes the diagram is correct and im configured nearly the same apart from my
SBS internal-nic has gateway of ip to the internal router (im upgrading to
SBS so all clients currently connect & gateway through the "internal router"
which has it OWN adsl connect).

I will clear the SBS "internal" NIC gateway "field"

I can see why your confused with me having 2 adsl routers, but its so I can
send you this post!!!

Ive not yet added the clients (inc this pc) to the SBS AD. Interestingly i
can ping the SBS by name and IP but not the other way round, why is this?

Let me try the removal of gateway IP field on the internal nic and get a
copy of the ipconfig.

Quick Q regarding the diagram, both the internal and external NIC ip dns
"fields" state: IP address of the server...... Which server? currently these
are as the sbs-wizard asked for pointed at my ISPs DNS IPs....... If I use
my ISPs DNS IPs in the SBS external nic, should I then just have a loopback
on the internal nic 127.0.0.1??.... Or setup DNS properly in admin tools
with foward lookups etc??

back in a mo

gt; Quick Q regarding the diagram, both the internal and external NIC ip dns

I'm assuming you get a dynamic IP (public) IP address from your ISP. I'm
also assuming you have SBS 2003 Standard. I'm alos assumign that you have
the 2 NICs in your SBS server, and that you have configured them per the
diagram at the web site I posted, and that you have run CEICW and enter your
ISP's DNS nameservers as forwarders when it asked for them. You can do
everything (except setting up the external NIC IP address, Subnet Mask,
Default Gateway and DNS server) within the CEICW wizard. With SBS , don't
do things "manually"... let the wizards do it for you.

The "IP address of the server" is that of the internal NIC on the SBS 2003
server (default would be 192.168.16.2).

i Merv, You were spot on, removing the internal gateway field solved the
internal name resolution!!

However internet setup wiz still reported an error. Tried installing premium
disk 6 and it reported an error with networking.

Like you say, the wizard do more, than the simple answers one gives would
suggest.

Im on my 3rd full reinstall. This time both nics were in at the start and
ive made a note that SBS earmarks the internal nic early on in preceedings.
I also realise from your last post that the dns entries in the wizard arent
for the nic!!

Ive also noticed that changes to nic dont occur without a reboot.

Fingers crossed 3rd time lucky!

Thanks for your help!

ou're gettin' there JD! This is NOT wasted time. A general rule with SBS
is to plan on installing it 3 times:

The first time to see what the install process is all about.
The second time to take detailed notes.
The third time to verify the setup, selections and any notes you have so you
can "document" your network.

e still need the output of 'ipconfig /all > c:\ipconfig.txt' from the
server.

I suspect the OP has both NICs in the same subnet.

Me, too. The wording of the original post _suggested_ both NICs are on
192.168.1.x.

Sorry, tried to send you the config from the SBS server, but despite having
succeeded in setting it up on the the third attempt, it tries to post to the
newsgroup through "O-express" over the "internal" line.

This is most strange as IExplorer happily knows that the external nic is the
one to use!!!!

The setup is now as follows:

Internal NIC:
static IP = 192.168.1.111
Subnet = 255.255.255.0
Gateway = NULL
DNS = 127.0.0.1

External NIC:
static IP = 192.168.1.101
Subnet = 255.255.255.0
Gateway = 192.168.1.10
DNS = 192.168.1.111 (note wizard entries were pointed to IPs DNS servers!)

Should the External NIC not have a loop DNS entry??? I didnt enter the
192.168.1.111 in the adapter properties!!

plainly my ADSL router is 192.168.1.10
Ive created a DHCP range allocation for the intranet of 192.168.1.120 to
250 as all my routers and CCTV-network cameras are static below .100

Is this OK?

JD,

As SG and Owen pointed out, your internal external NICs MUST be in different
subnet if your physical setup is per the diagram at:.
http://www.yqcomputer.com/

In general, the easiest to change is the external subnet. You can leave
your internal subnet at 192.168.1.x but you must change your external subnet
to something different (like 192.168.16.x, 192.168.2.x, 192.168.100.x,
etc.). (See the difference in the 3rd octet)? This means changing the
subnet information on the external NIC and the LAN side of the router. And
let the SBS server handle DHCP (if you don't already).

Again, follow the diagram above and use the wizards.

you have both NICs in the same subnet, WINSOCK is confused about which
should handle the traffic.

NOTE: What you refer to as 'subnet' below is actually the 'subnet mask'.
Mask operations are a bit level AND operation (you need basic BINARY skills
to interpret them correctly).

Have another look at the Lovely M&M(&M) diagrams. You will note that one
interface has 192.168.x.z/24 and the other has 192.168.y.z/24 (NOTE: /24 is
just shorthand for 255.255.255.0, 24 bits,
11111111.11111111.11111111.00000000). The two interfaces are in seperate
subnets because x and y are different.

Connect your 'external' NIC to the router directly. Connect your 'internal'
NIC to your network switch. Run the 'Change Server IP Address' Wizard from
the 'Internet and email' section of the SBS console, putting the 'internal'
NIC into a different subnet, say 192.168.16.z/24. Then run the CEICW. All
your problems will disappear.

I disagree, STRONGLY.

It is easier and better to change the 'internal' NIC. The 'Change Server IP
Address' wizard not only changes it for you but also changes service
bindings and associated items (DNS reverse lookup), while avoiding the
necessity of changing the router IP.

Once the 'external' NIC is connected directly to the router, and the 'Change
Server IP Address' and CEICW have been completed we'll have another properly
configured SBS, and associated happy camper.

low down you guys!!

OK, Subnets, always confuse me, something I need to read up on! I would like
to extend my IP range and have seperate subnets, but Im not sure how it
applies...... if I change the 3rd box to 254 rather than 255 I get to use
the 3rd box IP numbers dont I? So whys my 4th box got a 0 in it???

Queries
It would be less scary to change the external IP-Subnet mask

When installing SBS, it was notably concerned with the internal nic and not
the external one, therefore it suggests this is the problem area.... ie
global changes are made rather than what appears in the nic properties.

What does CEICW mean??? I dont know what BTW means either!

The argument regarding the router is disengenuos in my case, as I have 10
devices on my internal network with static IPs and subnets!, will I need to
change them all over to the new subnet??

Yes SBS is now handling DHCP, its bloody good at it to, normally theres a
few gliches with different models of wifi/routers on my LAN that SBS has
overcome!

Which leads to an additional query about the internal routers, they all have
"static route" options and RIP1,2 options. Does this static route play a
part, should I point the route at the DHCP/SBS?? And what of RIP should I
enable or disable? 1 or 2

Thanks

Jonathan

Post by jd » Wed, 18 Jan 2006 07:14:44

k read up on subnets, can the server internal IP remain the same, ie, can I
just change the subnet to 255.255.254.0 from 255.255.255.0 and leave the SBS
internal IP as is?

Would this still allow static IP routers and APs on the ..255./24 subnet
access to the 254./24 subnet and I would have a 510 IP address pool for
SBS-dhcp!?!

The external nic would remain on 255.255.255.0
The external gateway router would be 255.255.255.0

The internal nic would be changed to 255.255.254.0
**The internal routers and APs would be 255.255.255.0**

The DHCP cleints would become 255.255.254.0

Have I got this right now? Or should I move the static IP routers over to
...255.0 aswell?

Just curious, thanks Jonathan
