    I am creating a lab for familiarizing myself with a few protocols. My goal is to produce a server offering dhcp, dns, & http to a client (in this case the client is through a Dlink router). The physical architecture of the network is:

    comcast ]---->cable modem]---->Linksys router]---->

    Form the LAN I have an interface (eth0) on my RH9 set as a dhcp client on the network.

    My RH9 box is multi-homed. Eth1 is and offers DHCP, DNS, and HTTP to clients on that side of the network. DHCP and HTTP is working great but I have hit the wall on the DNS.

    Currently my short term goal is to resolve the requests to the TwelxNet domain ( to

    My long term goal is to forward DNS requests through to the network and then to comcast.

    Any ideas would be welcome.
