Hello, i own an asus RT-N66U with an internal 32GB microsd card. And i wonder if and how it is possible to make the following thing : I have a webserver on a vlan. If this webserver is unavailable, can the router serve a deffault web page "under maintenance" that come from the sdcard ? If someone ask for the domain test.tld, can the router intercept the request and serve page from the sdcard ? And if the server is up, just forwardevery other requests to the server. Thanks.
