We have a router (8 ports) that serves our church (it also is our modem with ADSL2 etc) and handles our DHCP services.
I've needed to extend our network to accomodate another 2 ports, so an extra router was bought (8 ports), installed with OpenWRT. We need this router to be a switch but use a different DNS server due to the business requirements.
I'm trying to workout how to configure the OpenWRT router (192.168.1.x) so that it still see's our core NAS (192.168.0.x) but any machines connecting to it uses the DNS's set on it rather than the Google DNS servers (or ISP ones) on the main router. It would also be nice for it to reside on the 192.168.0.x subnet (maybe .100+)
Is it as simple as turning off DHCP on the OpenWRT router and setting up the DNS or is there something else I need to do? I'd still like to have a static IP for the OpenWRT router so I can configure it via the web interface (Luci).
Trying it out earlier - disable DHCP, giving it a static IP and restarting, yielded no accessible IP for the router. So I had to reset the router.
Any ideas would be greatly appreciated.
