Re: 2 NIC SBS2003R2 LAN/WAN Firewall Router Connection Failure

both MS and VMWare have free versions of their virtualisation products.

http://www.microsoft.com/windowsserversystem/virtualserver/default.mspx
http://www.vmware.com/products/free_virtualization.html

I have to admit to a preference for VMWare Server which can only be
installed on a server OS. You may note that MS Virtual Server is not 'for
production use' when installed on a non-server OS, that's OK we're not using
it for production.

Thank you for all the links - I'll work my way through them over the
weekend.

I like the idea of a little test lab - I have some spare hardware knocking
around. You've mentioned the virtualisation term - I don't know where to
start with this, but I guess that's another topic for internet searching.

Thanks very much.

I don't really know of any 'basic IP networking' tutorials/books but it
sounds like a great search term :-)

I've asked the other SBS MVP's to comment on the current status of SBS
books. Not having paid much attention to such but generaly being
'involved'
I suggest that any I am aware of are getting a bit dated, I'm hoping
someone
proves me wrong.

SBS resources:

start here

or maybe here
http://www.sbs-rocks.com/sbs2k3/sbs2003-1.htm

don't skip this one

and goto here

and here
http://www.smallbizserver.net/

and more from Susan
http://www.sbslinks.com/

I actually threw that list together as a 'primer' on SBS installation but
of
course there is a lot of content across the sites.

The number one thing I suggest is to put a test/lab/play system together.
Grab some old hardware or a virtualisation system and do a couple of
installs, play with it till you break it (OH, I won't do that on the real
system), format and give it another go, use it to test your Disater
Recovery
scenario, non DR restores, patching etc...

OK, I've just gone and followed your instructions.

a) I connected directly to the router and changed its LAN side subnet
mask
(I hope I'm using the right terms) from 255.255.0.0 to 255.255.255.0 .
b) I changed its static IP address to your suggestion.
c) I changed the SBS external IP settings as you suggest.
d) I changed the SBS internal IP settings as you suggest.

It workes perfectly. Clients can see the Internet. The SBS Server can
see
clients and the Internet. Clients and the SBS Server can reach the
router.

Perfect.

I feel that I should learn more about networking and SBS fundamentals.
Are
there any recommended books or websites which can help to educate
someone
as
ignorant as me so I stop making such basic mistakes?

Thanks very much for your help.

Hello Marcus,

Thank you for posting here. And thanks for Merv's inputs.

According to your description, I understand that you can not access
your
router from internal client or SBS. If I have misunderstood the
problem,
please don't hesitate to let me know.

Based on my research, I suggest we try the following steps to see if
we
can
resolve this issue:

1. Please contact your router vendor to check the settings in the
router,
may be there are some rule deny the access from some IP addresses or
subnet.

2. Merv's inputs is correct, your network configuration need to
change:

Please change the IP configuration like following:

Firewall-Router (public WAN side), Static Public IP from your ISP

Firewall-Router (private LAN side), Static IP 192.168.1.1 subnet
mask
255.255.255.0
SBS External NIC, Static IP 192.168.1.2 subnet mask 255.255.255.0
gateway 192.168.1.1

SBS Internal NIC, Static IP 192.168.16.2 subnet mask 255.255.255.0
Workstations, Dynamic IPs 192.168.16.x subnet mask 255.255.255.0
gateway
192.168.16.2

Note: the IP192.168.16.2 subnet mask 255.255.255.0 and IP 192.168.1.1
subnet mask 255.255.255.0 are not in same subnet, but in different
subnets.

3. Run the CEICW
Go through the follow KB and Rerun CEICW again carefully.

How to configure Internet access in Windows Small Business Server 2003
http://support.microsoft.com/kb/825763/en-us

Additional:
1. Please do not uses IP address 192.165.0.0, this is not private IP.
The
private IP is 192.168.0.0/16.

2. We do not need to add static route on internal clients or SBS.

Hope these steps will give you some help.

Thanks and have a nice day!

Best regards,

| HI,
|
| That's not my configuration. If you look at the diagram, both the
WAN
NIC
| and the LAN NIC are on the same subnet.
|
| My WAN NIC and LAN NIC are on separate subnets; the former on
255.255.0.0
| the latter on 255.255.255.0.
|
| I think it's because of the different subnets that the clients and
server
| cannot communicate with the router.
|
| That's why I asked about static routes, the router table and so on.
|
| Oh, and I can't put the WAN NIC on the same subnet; I've tried and
it
won't
| work.
|
| Happy to consider any other ideas...
