    From my understanding, to get WPAD working, i need to create a DNS entry for "wpad" pointing to the server.

    Is this possible on my WRT54GL?

    If not can i configure WPAD using DHCP?

    Heres the steps for setting it up on a Windows DHCP server:

    I dunno how to formulate it in the DHCP setup that Tomato uses, but, in general, you would add an entry like this to /etc/dhcpd.conf:

    option proxy-auto-detect code 252 = text;

    and then, under your shared-net definition

    option proxy-auto-detect "http://your.server.name/wpad.dat:80";

    However, you may not need to do that; Browsers, and I dunno if it's ALL browsers, but I think so, should go looking for http://wpad.whatever.your.domainname/wpad.dat when they are set to auto detect proxy. Therefore, you need to make sure your http server has the alias or name wpad, and that a file called wpad.dat (which contains proxy.pac scripting) exist in the root of your web.

    From http://www.wpad.com/

    How does it know what domain name to look up?

    The domain of the computer the browser is running on - hardcoded into the network settings, or obtained via DHCP.

    I guess if the computer does not have a domain assigned, the browser may just go looking for "http://wpad/wpad.dat", i.e. the computer with the name "wpad".
