Active Directory + Belkin Router

| This is my home network.
Comcast Cable ISP - Motorola SB4200 SURFboard Cable Modem
Belkin Model FSD5230-4 Router/Switch (4-Port)- Current Firmware Version: V1.20.001
Firmware Date: 07-19-2002
Belkin Model Wireless DSL/Gateway Router/Switch Model F5D6231-4(4-Port)(Configured as Access Point Only - No NAT/DHCP/DNS)
Windows 2000 Advanced Server SP4 running Active Directory, DNS for the LAN (configured to forward to the 1'st Router)
1 Windows XP Pro - Client - PC
3 Windows 2000 - Client - PC
1 Windows XP Pro - Client - Laptop -Wireless connection
1 OpenBSD 3.3 GENERIC#44 i386 - Client (No services)
I decided to install RIS on the server so I can bring up a couple more machines with SP4 Slipstreamed in the installation files over my 100MB LAN.
I realized I needed to enable the DHCP server and that's when I noticed I have a problem. The Belkin Router functions quite well as the DHCP server and despite numerous attempts at assigning a LAN Scope to include only the server (assign it that static IP) and then configure the clients to use DHCP, the clients will only respond if I disable DHCP on the Router. Then they get their IP's from the server and can access resources but the DNS forwarding doesnt'appear to work and only the server gets out to the Internet.
My RIS client also got an F12 Network Boot Prompt from the boot disk I created but then the OS Chooser screen seemed to hang...
My question is if it is possible to run an Active Directory DHCP server behind a broadband Router that is functioning as a DHCP server in support of RIS, and if so, any suggestions?
Thanks alot!
Scott

| You are going to need to disable DHCP on your router for your experiments with RIS to function properly.
Your bets bet is to statically configure your router and use your W2K DHCP server to take over all ip configuration settings for your dynamic clients.
Check your router external settings and determine what its "wan" ip address and lease expiration are from the provider. Also determine how often they actually change. Pay special attention to the DNS Server addresses. If they are relatively static, simply have your W2K DHCP server configure your clients with those addresses. | |

| You will need to use NAT if you want to get from all of your computers out to the INTERNET.
When you configure your router statically, make sure that it is translating all of the addresses within the scope that you are leasing.
I am not sure that all home routers allow that level of configuration when you disable DHCP on the router. (chances are that if your router states that it supports multiple users to a single broadband service then NAT is always on.
My guess is that you are configuring your clients basic ip settings, but not dynamically setting up DNS on the client. | |

| I use a router with DSL and Win2000 DHCP. You have DNS running on one of your servers and have it forward to your ISP DNS servers. DHCP should be configured to set DNS to the local server and the gateway to the private address of the router. What you want to do should not be a problem. | |

| Well using the ISP's DNS servers makes alot of sense...thanks!
Do you think I should have the router only spit out one IP (limit the DHCP scope to say 192.168.2.7) and put that in static for my server? Then create a scope like 192.168.2.8 - 192.168.50 on the Windows 2K DHCP server and have it handle all the DHCP requests?
If I disable DHCP on the router it won't give me an IP unless I switch NIC's with the workstation I registered with (cloned the MAC for the router.
Thanks for your help guys, this is a fun project!

| Your server will have a fixed address, one that you maunaully configure in the properties of its lan connection. DHCP on the router will not be active. If your server and the DHCP scope you configure are on the same subnet as your router and each client has the correct gateway and DNS settings, whether manually or automatically configured, all should work fine.
If you have to use a particular MAC address on the router, that is likely on the public interface for the benefit of your ISP. |
