I have following setup.
Hotspot is configured on RB750, It does not offer internet services , just to redirect users to my local Radius billing web page.. So when users comes on LAN, he gets ip , gw and dns from rb750.
2nd Mikrotik is configured as pppoe server, when users dials he gets pppoe poool ip and my linux box dns server ip. But the problem is all users DNS requests goes to rb750, which i don't want.
I want to force pppoe users to use my Linux BOX as Default DNS server ? How to do this ?
