Small Business Server, Linksys DSL Router, DHCP, Can't see both server and router

Posted on 2003-03-18

Running Small Business Server 2000 w/ 5 clients. I have assigned (on Server 2000) workstations with ip addresses in the range of thru 255. When I use a static IP address on a workstation, I am able to access the server, but not the internet thru the router. If I change to "obtain IP address automatically" I am able to access the internet, but not the server (when Router is set to DHCP enabled).
I have tried disabling the DHCP on the router and assigning the router an ip address in the range listed with Active Directory on the Server, but obviosly still having problems.
My question is: Do I need to somehow inform the server of the router, and if so how?

Any help would be appreciated.

First off I think you have 2 differnt subnet going server Linksys

I think the eazy thing to do is put the Server at an address in the Linksys subnet ( and leave the Linkys to hand out DHCP address ( I'm thinking they start at

I suggest using static ip's, but you must enter all of the correct info
default gateway (the linksys router LAN interface)
and dns server entries (use the ones p[rovided by your isp, or less preferably, the linksys LAN interface, by default it is but if you have changed it, then use the value you changed it to)

A couple of solutions here.
1. Disable DHCP on the router and let your server handle the DHCP

2. Disable DHCP on the server and let the router handle it

3. Disable DHCP on both and configure each machine to have static address as stevenlewis

vwinkeler  is correct about 2 differant networks .

I would opt for option #2 for the less administrative overhead required when any changes are required

Thanks for the help. I disabled DHCP on the server, enabled DHCP on the router, and configured the routers' LAN IP address to which is within the range we set on the server. I can now access web and server as long as workstation is set to obtain IP and DNS automatically.

Settings I attempted on workstation:

IP address:
subnet mask:
default gateway: (left blank and tried listed Gateway on router)

DNS server address: (server address)
alternate :  left blank

Can you tell me what I'm missing? I would like to have static ip addresses for each workstation.

> (server address)
should be either the isp's dns server or your router interface
preferably your isp's dns
definately not your servers ip (unless youhave setup dns correctly

>default gateway: (left blank and tried listed Gateway on router)
you need to define a gateway (the door out of the network to the internet) and it must be the router interface

to test use ping from a prompt
from a prompt on the host type
ping 192.168.0.x Where x is the ip of the client)
ping the router
ping www.experts-exchange.com
please post the results here

Unfortunately I don't understand everything about the network (that will improve over time, I guess), but I changed the default gateway on the workstation to the same IP address as the LAN IP address on the router and listed DNS servers as the same as those listed on router.

Happily it all seems to work. Thanks tons.

I'm sure it will! We all started out not knowing much, and learning along the way.
