Hi,
I'm trying to setup my network at home. The network setup currently looks like this:
* There is a Non-Configurable Internet Router called "Office Router"
* There is a Configurable Internet Router called "Private Router"
* There are several computers that connect to the Office Router via WLAN or LAN (using the DHCP service of the Office Router).
* There are several computers that connect to the "Private Router" using LAN / WLAN.
* There is a ChromeCast that should be using the Internet of "Private Router". ChromeCast can ONLY work with DHCP - no static configuration possible.
* There is a NAS and a printer (connected via LAN) that should be accessible from all computers in both networks.
-----------------------------------------------
My current setup is as follows:
* All computers that should connect to the internet via the "Office Router" use DHCP.
* The "Private Router" is connected via LAN to a dedicated router running DD-WRT.
* The DD-WRT router runs a WIFI.
* The DD-WRT router is set to "Bridged Mode" and connects the "Office" network to the "Private" one.
* Clients that should connect to the internet using the "Private Router" are configured with Static IP Addresses, and use the DD-WRT Router as their Standard-Gateway.
So far this setup works, but has two major downsides:
* All devices that should use the "Private Router's" Internet must be configured to use static IP addresses
* The ChromeCast can ONLY connect through the "Office Router's" Internet as this is the one running the DHCP service.
-------------------------
The optimal setup would be:
* All devices should be configured using DHCP.
* There should be two DHCP instances:
** One that serves the "Private" devices
** Another one that serves the "Office" devices.
* The DD-WRT device should route traffic between these two networks, so that:
** Devices from the Office network can connect to the Private network and vice versa (Private computers should be able to access the NAS and the Office printer)
** Devices served via the Office DHCP group should connect to the internet using the Office router
** Devices served via the Private DHCP group should connect to the internet using the Private router

Connect the WAN port of the dd-wrt router to a LAN port of the Office Router.
Connect a LAN port of the dd-wrt router to a LAN port of the Private router.
Set the router in "Router" Mode.
What ip addresses is used?
Use separate sub-nets for Office and Private side.
I have a few additional questions:
* Where does the DHCP server for the private network run? On the Internet router ot the DDWRT one?
* What Gateway do I specify in the DDWRT Setup page?
* How should the DHCP service be configured?
* Should I enable dynamic routing or disable it. If enabled, on which interfaces?
After setting up everything I could not access any device in the office network. Tracert shows that the DDWRT router did not forward requests to the office nework.
I'm sorry for asking stupid questions but I am unfamiliar with all the options in DDWRT.
Would it be possible to describe the required settings a bit more in detail?
That actually sounds really easy.
