Redirecting users to the router home page

I have set up a redirect rule, and it successfully redirects people to the router home page when they use Internet Explorer 6, but if people are using Firefox 1.0, they get an 404 error.
Not sure what the problem is, doesn’t seem to be anything wrong with the router, since it redirects users of Internet Explorer.
Just wondered if anything had similiar issues.

what kind of redirect rule is it and to where are you redirecting your users. maybe the rule is incorrect or there is something wrong with the page

whats the sense of it?

it is possible to redirect clients, witch arp is disabled or any kind marked, to router homepage?
