I've set up RouterOS on a box. I'm planning to offer free or paid WiFi access through Hotspot.

The Hotspot seems to be working just fine (on the bench connected to a cable pipe) with different user profiles, i.e. free, paid or unlimited, etc. Even though the cable connection is DHCP.

But,I plan to use the box at a DSL PPPoE pipe with dynamic addressing.
At the DSL PPPoE with a different box, I've tried putting their modem (AT&T) in bridge mode to eliminate the extra NAT.
Which I believe can break a few apps.

My dilemna is:

Since I've got a DSL PPPoE pipe with non-static IP addressing. I was informed I could run PPPoE on the RouterOS box.

My question is: Can I still use the HotSpot login page with local authentication (not-radius).
Do I simply install a PPPoE client on the RouterOS "public" interface connected to their gateway/modem?
I'm not clear as to whether or not I need to put both a PPPoE server AND client on the Box with Hotspot.
I guess a Static address would solve the problem, but it's not my call to pay the slight extra for Static IP.
Thanks

Hi, you can have both Hotspot and PPoE in the same Mikrotik, but it's recommended to have each one in a different interface.

So, If I put the PPPoE client on the Wan and use Hotspot on Lan, that's all it takes?
The question was: Do I need both a client and Server PPPoE?
Thanks

Yes you can.

Yes.

No you do not. Your mikrotik box is a pppoe client (for wan) as well as a hotspot server (for lan). That's fine.

I should have thought those questions through beforehand, common sense.
Thanks for the help.
