Posted: Thu Sep 21, 2017 18:28 Post subject: Cascading Routers, Separate Networks with different DNS
I have two separate routers both running recent versions of DD-WRT firmware.
What I'd like to do is use one router (Wifi and Ethernet) for the devices the wife and I use and have the second router (Wifi and Ethernet) be available for the kids to use. On the router for the children I would like to use OpenDNS to filter their content.
Is this possible?
Is this a good idea?
What type of changes should I make to the router's settings?
Currently I have a LAN port on router #1 running to the WAN port on router #2.
Router #1
Connection Type: DHCP
Mode: Gateway
Local Network settings:
192.168.1.1
255.255.255.0
0.0.0.0
Router #2
Connection Type: Static IP
192.168.1.2
255.255.255.0
192.168.1.1
Mode: Gateway
Local Network Settings:
192.168.2.1
255.255.255.0
192.168.1.1
Yea you can do that if you wanted or you could do it all from one router also.
But from what you are showing I'll make a couple suggestions -
Router 2 ... leave its WAN connection type as DHCP.
if you want it to have the 192.168.1.2 IP put that as a static lease in router 1.
Just get router 2 WAN MAC address to put along with static IP.
Router 2 is showing as gateway mode so its LAN gateway is not 192.168.1.1... It would
be its own IP 192.168.2.1 ... ok
Set router 2 static DNS to whatever you want but you must make sure 'Forced DNS' is
not enabled on router 1 .... I think that should work.
If I was determined to use two routers I would just set #2 up as a WAP and either unbridge its
physical wireless or create an unbridged VAP.
Using one router to do it all just search for creating a guest network.
Note: If you are using a router with 'Recursive DNS' and it is enabled on the main router all DNS will go thru it.
You would have to turn that off to allow use of other DNS for other devices.
Thank you for your suggestions.
I have it working correctly now, for the most part.
I researched the option for having a guest network prior to the idea for using the second router, but not all of their devices are WiFi capable (older BluRay players, etc. <- There are network drops in their rooms to bypass the no WiFi limitation).

Yea set MAC & IP in static leases on main router so the 2nd router will always have same IP. This is important --- by default anything connected to the 2nd router can access devices on main. You will need to add firewall rules to block this if you need to. I'm not going to try typing out the rule from memory... besides I'm using the phone and it's interface is terrible in these 15 year old forums.
Search for firewall to block WAN subnet and that prolly fix you.
