Computers involved:

"netgate" - This computer is running bind9 and ldap. I want to configure this as the primary DNS service. In the end I also want this computer to host roaming directories (file synchronization across computers)

"windows" - This computer is running Vista Ultimate, and after I get all the linux boxes playing nice I may try to incorporate this comp.

"linux1" - This computer (so far) uses netgate's DNS lookup, I know this since the connection dies when I turn off bind9 or terminate netgate's internet.

"linux2" - This computer (so far) should be using netgate's DNS lookup, but either doesn't or is automatically finding a backup DNS server, because the connection is still good regardless of netgate's status.

I'm using DD-WRT on my WRT54G V2.0.

How do I set DD-WRT to use netgate as the primary lookup and my ISPs as the secondary/tertiary? I'd like to have this all done at the router level, so that when other people connect they automatically use netgate as the primary lookup.

My endgame (though maybe not entirely related) is:

Remote comp -> Internet-> netgate (auth) -> Local computer desired.

Any thoughts?
Thanks!

Nobody knows how to set up DNS on dd-wrt? It's linux firmware so I think it's relevant to the forum. It seems like it'd be straightforward enough (and it was on the original linksys firmware) but apparently I'm doing something wrong :P

It might help if you explain what you have done with DD-WRT so far and what failures and error messages you are getting.

Do you have DD-WRT already installed on the linksys router?
Not much help here of course, but I am just bumping this back up to the top, because I would like to see a good answer to this question.

I do already have DD-WRT installed on the linksys router.

Under Setup->Basic Setup (on that page Network Setup->Network Address Server Settings (DHCP)) I input the local IP of the computer I want to use as the DNS server. As I stated in previous posts, however, it doesn't seem that the router is making that IP the priority. I also set "Local DNS" to the same local IP, still no results.

I'm not receiving any errors, but I'm not receiving expected results.

Googling dd-wrt dns pulls up a ton of material pointing to DNSmasq and OPENDNS and the editing of /etc/hosts
Good luck with your project!
