    Has anyone ever set up a Windows 2000 server, acting as the Domain Controller for the network, behind a Linksys router? Considering that the router seems to require that any IP device that is connected to it, get it's IP address atomatically, and yet a Domain Controller really needs to have a static IP address, I can foresee some real communications issues between the Domain Controller and the Workstations it's serving. Does anyone know if there is a work around for this problem. Will the Domain Controller still communicate properly with the network workstations if the Domain Controller has a Dynamic IP. Will it still comunicate with the router if I set up the Domain Controller with a static IP and simply exclude that particular IP address from the range of assignable IP addresses when I configure the router as a DHCP servere?

    You definately are on the right track. The DC requires a static address. It will all work seemlessly as long as you give the DC a static IP and let the router act as the DHCP server. The workstation IPs rarely change so you might want to add static DNS entries on the DC.

    My situation is as follows. My DC has an address of and the router DHCP server will only allocate addresses from 50 to 65. I've had zero problems since implementing this set up.

    You can also disable dhcp in the WRT and have the DC handle it. Just make sure that the DC's DHCP server gives out the correct Default Gateway. (Router's IP address.)

    Since DNS is important in a domain environment however you end up configuring things make sure the workstations use the DC as their DNS server.

    WIndows DC behind a Linksys WRT54GL

    I am using Dd-WRT v23 Sp1, I am working on getting a VLAN configured (10.0.0.x) Is it possible do have a DC running DHCP and DNS on the VLAN, and have IP's handed out by the WRT54GL for the LAN 192.168.x.x. I am a newbie to DD-WRT. Please excuse my ignorance.

    Much thanks,

    Many...many...many times. NT4, 2K, 2K3, SBS2K, SBS2K3, single NIC and multi-homed too.

    Here a quick little article I scribbled about AD, DNS, routers...

    I have a win2k3 server with dns and it works fine, as long as you let it do all of the DHCP. I am sure it would work the other way, but its just not as easy. Assuming that the DNS server is on all the time anyways why not just let it do the gateway and dns and make the WRT an accesspoint only. It seems to work well for me. I use it to "share" a dialup line and god knows that is a feat in itself (configure RRAS with ISA 2004 and you know what I mean).
