Hi all... I've been wondering about this for a while a decided to post here to ask for advice... I've a simple network to set up based on windows server 2008 r2 and would like to know which of the two solutions (if they are correct first) is the better for a simple lan.

Hope you understand the following layouts:


Scenario A:
<*Internet*><----->ADSL/Modem Router<----->Switch<----->Server, Clients

ADSL/Modem router
-------------------------
IP: 192.168.1.1/255.255.255.0
DHCP Scope: 192.168.1.10...192.168.1.80/255.255.255.0

Server
--------
AD Win2k8 with DNS and RRAS
NIC(Static): 192.168.1.2/255.255.255.0
Gateway: 192.168.1.1
DNS1: 192.168.1.2
DNS2: 192.168.1.1
RRAS: Wizard configured for VPN access only

Clients
---------
5-10 clients configured through DHCP
IP: 192.168.1.10...192.168.1.80/255.255.255.0
Gateway: 192.168.1.1
DNS: 192.168.1.2

<*Internet*><----->ADSL/Modem Router<----->Server(NIC2(Static)<----->Server<----->Server(NIC1(Static))<----->Switch<----->Clients

ADSL/Modem router

Server(NIC2(Static))
-------------------------
IP: 192.168.11.2/255.255.255.0

It's a small, simple setup... I'd go w\ something like your version A.

I agree with itadakimasu.
I have a very similar setup running.
This allows me to service the 08 server and not lose DHCP while it is happening.
Look for a good quality router and put it on a battery.
