You might try hacking the code to create your own version of DD-WRT and submitting it back to them, or find something else, like your Fedora box, to do your DHCP assignments (just to help bring this thread back on-topic. <Grin>) Seriously, I think asking a little SOHO router to handle static DHCP assignments for 15 or 20 devices is a bit much, then again, I've never tried this, so I don't know. I only have two PCs that I care about having static assignments... my linux box and my wife's PC. Hell, her PC could have a random IP for all it matters... :-) Point is, you may be trying to use a hammer to put a screw into a wall. It might do the job, but it's not really the right tool. In this case, you might want to look at finding something else to handle your DHCP assignments. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
