as far as the Names matching, I believe the Endpoints add a number to the gateway name.
I.E. the gateway name may be ACgw then the first endpoint will be ACgw00, then ACgw01 for the second endpoint and so on.
As far as the settings go, I've had the best luck modifying the config file with notepad, then pushing it to the gateway with the provided bootp program.
If you have a newer firmware version, the web interface seems to work ok.
