R7000 router showing router reset page to WAN

> I am trying to host a website [...]

   Ok.  Which?  Running on what?

> [...] and I have setup port forwarding on my Dynamic DNS [...]

   I don't know what that means.  Port forwarding and Dynamic DNS are
two different things.

> [...] as well as my router, [...]

   How, exactly?  Actual Address Reservation and Port-Forwarding rules?

> [...] NETGEARS router reset page shows up [...]

   What's a "NETGEARS router reset page"?  Are there words on it?

> [...] when people are redirected from the open internet. [...]

   Who, where, gets "redirected" how, to what, from what?

   None of that is a useful problem description.  It does not say what
you did.  It does not say what happened when you did it.  As usual,
showing actual actions (commands) with their actual results (error
messages, LED indicators, ...) can be more helpful than vague
descriptions or interpretations.

> [...] Does anyone know how to disable NETGEARS router reset page [...]

   If I had any idea what that meant, then I might be able to answer it.

   Note that if you're specifying your router's WAN/Internet IP address
from a system on your LAN, then you might get unexpected results,
different from what would happen from a system in the outside world.
