You are not going to get this to work this way. You need to have your ADSL → MikroTik → Wireless. Look at the 751 boards. They are more of what you need.

Actually it’s doable. I have such setup at home (using RB750 – still waiting for that RB751! :slight_smile: ).

There are two scenarios and it all depends if your ADSL/WiFi router supports PPoE Relay (or pass through).

  1. If it does support PPoE Relay/passthrough.

Disable DHCP server on your router, NAT and don’t make it connect to internet (leave any PPoE credentials blank). Turn on the PPoE relay and set its LAN IP manually to some IP address within whatever you’ll use in your network.
On MikroTik router: setup DHCP server, add new PPoE Client interface and set up there your PPoE credentials (provided to you by your ISP). Setup NAT with the WAN port being the PPoE Client interface you’ve added.
You just need one cable between your ADSL/WiFi router and MikroTik router. In this scenario the ADSL router is dumbed down to act as an ADSL modem and an WiFi access point.

  1. If it does NOT support PPoE relay/passtrhough.

You have two options here as well, depending if your router supports adding static routes or not. If it does not it becomes messy as you’ll have double NAT setup (one NAT on your ADSL/WiFi and second one on your MikroTik. In this case you still want DHCP server to be turned off on your ADSL router as the gateway for anyone connecting through the WiFi should be your MikroTik which in turn routes the traffic through ADSL router.
I won’t go into detail how to set it up this way but you should have an idea if you have some networking experience.

Would this work if I put the ADSL modem in bridge mode, and is there any tuturial on how to do this setup

I am trying to set exactly this up with a Netgear 300N Wireless ADSL modem and a Mikrotik 750 routerboard.
Want to use the Mikrotik box purely for authentication for my coffe shop.

Thanks in Advance for any light you can shine on the subject.
