I just had changed my dynamic IP  to a static IP.
on the router i entered my statik IP (for example 111.222.333.184).
i entered subnet mask of 255.255.255.0
i entered default gateway of 111.222.333.1
the router has the router ip of 192.168.1.1with a subnet of 255.255.255.0 :::is that correct???
then under network setup---->network address server settings(DHCP):
the localDHCP is enabled
start IP is 192.168.1.100(only the 100 could be changed the rest is in bold black letters by the router-linksys)
DHCP address range is 192.168.1.100 to 192.168.1.149
the WINS is 0.0.0.0
Please advise

below are my settings
C:\Documents and Settings\Administrator>ipconfig /all

Hello j_rameses,
That should be okay, given you entered the correct IP address and Subnet mask for your external IP address on  your Firewall.

The reason only the 100 could be changed on your private IP address is because you are using a class C subnet mask.  The 255.255.255.0 means you can only have 254 IP addresses on your network (102.168.1.1-192.168.1.254).  If this is your home network, which I'm assuming it is, you shoulf be good to go.


Regards,

Rogiee

Rogiee,
This is for a small business.
I am running Small Business Server 2003 R2.
I changed the Default Gateway and the IP address for the internal LAN(nic card) to the same IP of the Preferred DNS of the External LAN.  Is this correct?  THe clients could access the internet but the server cannot.
Please advise what is the correct configuration for setting up the external and internal LAN.

No....

Your internal default gateway should be 192.168.1.1.....IP address of your server can be 192.168.1.10...

Change your server's DNS Server IPs to your preferred DNS (or you could use 4.2.2.2 and 4.2.2.1)

Rogiee,
So i then have to change the default gateway on the internal nic card to 192.168.1.1, correct?
And,
I should change the IP address of the internal nic to 192.168.1.104, correct?

Regarding:
"Change your server's DNS Server IPs to your preferred DNS (or you could use 4.2.2.2 and 4.2.2.1)"
are you saying that the internal nic preffered DNS should be the same # as the preferred DNS as the DNS of the external nic?
Please clarify, i really would like to have everything working correctly.

Rogiee, thank you.
I am thinking if maybe i should take a drive to the office and reconfigure the SBS.
Quick question i should now be able to ping the clients from the SBS, correct?
Because the clients could ping the SBS.

fellow experts, I have information you may not be privy to.

Looking at this information, I am beginning to think the author has ISA on the server and it is causing grief on DHCP, DNS, the website, pinging and other issues.

Author, there are rules to be set on an ISA firewall for pinging, DHCP, DNS, and all related issues you are running into.

Hello Rogie:

There are a number of issues on this network.

Topology:

internet>>modem>>wan side of router Nat to Lan side of router>>WAN side of server to LAN side of server>>clients and printers.

The NIC cards on the server were conflicting. Ramises called microsoft and had them configured.

As you can see there were two forms of NAT. But that's not all.

Software:
There are too many software firewalls were blocking services and server roles. Ramisis has Windows firewalls and ISA firewalls on clients and servers.

So, there were all kinds of port blocking problems and a couple NAT configurations to make in order to get things to work correctly.  

Hinting around the dual NIC configuration was right on the money. So you were "correct".

What I am trying to do to  help Ramisis is guide him on a step by step procedure. No sense in trying to fix the web page or mail  before network connectivity is 100&, right?

After the NIC configuration changes made by Microsoft, we are going to test connectivity and check out the routing, then configure ISA, bring up DHCP, DNS, make sure the master browser is working perfectly, bring up WSUS and make sure the LAN's mail and web page are working properly.  There are links provided above if you wish to join us. Right now we are on the link that bbao is helping on. I am monitoring while bbao is providing the fix.
