i have a small server running on my home network and it has always worked fine but the other day i cleared my router settings and am having problems putting them back. i have a linksys befsr41 router. my problem is this: i have set everything back to the way it was except for th filters. for some reason it wont let me change the filters such as block WAN request and filter internet nat redirection and so on. when i pick the setting i like and click apply i get a username and password prompt. no matter what i type in it just keeps popping up. i know its not a password problem, i really have no idea what it is though. ive changed firmware several times, reset to defaults and changed the password, nothing worked.
