I have a Belkin Belkin F5D7230-4 v1444 running DD-WRT v23 SP1 Final (05/16/06) micro and every time I try and set the DMZ option the router hangs in a continous loop of boots. I do a factory reset (using the button) and then reload the options as saved before I set the DMZ and I am back in business. I have tried this several times and every time I get the same result, as soon as I click on teh save settings for the DMZ option the router boots, lights flash starts appear to come online and then starts the boot process all over again.
