RB751u 2HnD custom home page

Hi everyone… I’m new in this world and I was hoping that you guys could help me with something.
Here is the thing… I have a RB751u 2HnD and I need to configure it so when someone connects to the wireless signal, the router redirects the user to a site(www.example.com). After that(and after logging), depending on if the user has enough “credits” the user can access the internet and surf it normally…if not, the router should block internet access to that user, allowing it only access to the home site(www.example.com)…

That’s it !!.. is even possible to do the above with this router?..
I would appreciate any kind of information regarding this subject…
Thanks !

PD: I’m using RouterOS 6.0rc1

Sounds like you need hotspot.

Thank you cbrown for that answer.
Yeah, that is what I was looking for… but I have some followup questions.

Based on what I know so far, if a want to have a custom landing page for the Hotspot, I have to upload it to the ftp server that is running inside the router under a special folder(named hotspot), but what if I want to have a database and keep track of what is going on?.. can I use a different website to control events like user/password, credits, etc?.

And also, supposing that I manage to get user/password → login from a different website… How can I monitor the bandwidth and/or data transferred of that user?.. knowing that the authentication it’s been done elsewhere but the router.

Thanks a lot…
I know that it’s a lot to dig in… =S
