I am running mikrotik dns relay on one of my rb750g routers. I have added a few urls that redirect people to internal servers.
I would like to know can i redirect all url request that has not been added to the dns list to one ip address?
Sounds like this would be much easier done with a Hotspot (unauthenticated users always get redirected to the login page, which in turn can redirect to any arbitrary URL). You can still via DNS fake out any IP address and allow traffic to them.
