I am trying to set up a small "lab" at home. Like many modern homes, I have a regular DSL service which comes with a 2Wire 3600HGV router, which acts also as a DHCP server.
I've got a problem with dnsmasq on my server everything but dns works on it, it currently gives out dhcp fine and points to the router etc however when i go to a website it wont find it, the dns is pointed to the server on the client machines.

Dnsmasq is a lightweight server designed to provide DNS (and optionally DHCP and TFTP) services to a small-scale network. It can serve the names of local machines which are not in the global DNS.
Making server for school. ISP is PPPoe. internet-modem/router-server-WAN(eth0)-LAN(eth2)-switch-clients. eth0 is dhcp. eth2 is static 10.10.0.1 255.255.255.0.
I am attemting to use dnsmasq to create dns caching and dhcp on LAN.
I commented out dns-dnsmasq in NM, downloaded and installed dnsmasq, and configured dnsmasq.conf, but no caching and no dhcp.
I took down my DHCP server to change some stuff, and after bringing it back up (down for 15 mins or so), I noticed that four other Ubuntu 12.04 servers set to use DHCP were unreachable. Running ifconfig on them returned just lo, so the eth0 and eth1 had been disabled.
I'm assuming the DHCP server missing caused them to shutdown the interface?
I have an existing LAN with a DHCP server already dishing out IP addresses.
For various reasons I cannot replace that server so it will still need to dish out IP addresses.
I've been experimenting with dnsmasq in proxy mode to provide PXE boot filenames.
Now I have dnsmasq chainloading iPXE ok, but I found that the problem with dnsmasq is that in proxy mode it won't send dhcp options down.
I just upgraded a 12.04 server to 12.10.
It was built with MAAS but no other servers had been added to its private network yet, but I confirmed that dnsmasq was setup correctly for dhcp and iptables for forwarding etc.
Now I have upgraded to 12.10, dhcp is no longer available and I found that dnsmasq was removed. :mad:
What is controlling dhcp now, and where do I edit the correct configuration.
The network was fine yesterday and as far as I know nothing has been changed or added. This morning some computers are connected to our domain but most of them are reporting limited connectivity. On checking our DHCP server we are getting this message.
Cannot find the DHCP Server:
The DHCP server you specified cannot be located.
I would like to use only dnsmasq to forward all dns requests to google's dns server and disable dhcp...
How can I achieve this result?
