    I'm trying to switch from a WRT54G to an E3000 router on a 10 mac 1 pc network for a business. Most are wireless but the mac server and a printer are hardwired. I've documented all the config info from the WRT54G. I'm using the web based config on the E3000 and entering all the WRT54G config where it allows. I didn't configure the WRT54G but it all seem rather straight forward.

    The connection is it a T1 through the phone carrier and no matter what I do I can't get any pc or mac to connect to the internet through the E3000. I can reconnect the WRT54G and it works. I even tried cloning the MAC address to no avail.

    Some differences in the E3000 is that there isn't an option to change it from a router to a gateway as the WRT54G was configured. Sorry I don't have this in front of me so I can't specify under exactly what menu that was under.

    I enter the static IP, subnet, DNS's by the Internet Setup config section then when I enter the Network Setup IP of set to DCHP and enter subnet 255.*.0 it automatically inserts the DNS numbers from Internet Setup and won't let me change it. Shouldn't 192.*... be the DNS for the LAN?

    NAT is turned on.

    I noticed that the server was in the DMZ on the old router which I don't plan on doing since that just doesn't sound like a good idea. Nor do I see a config place to do that.

    All the wireless client macs need to continuously be connected to the wired server to run a Filemaker DB.

    Any advice on this or migrating settings from the WRT54G to E3000 would be greatly appreciated.

    I should clarify that I am using for lan subnet.
