How to make a simple redirect to an external site using dd-wrt?

Question

network hardware

Good day.
Tell me, please, is it possible using only a router (in my case, TL-WR841ND, flashed with dd-wrt) to organize a simple redirect of connected users to an external url?
Neither authorization nor any restrictions are needed: the user connected, saw the proposed page, went where he needed.
