having trouble conecting to pppoe router on ether1 interface

The ether1 ip address of my mikrotik is 192.168.0.0/24 and i have a adsl router connected on that range. The wlan1 ip range is 192.168.8.0/24 and i have a friend that want to use the pppoe router that is connected on the 192.168.0.0/24 range.


The problem is that he cannot connect to the pppoe router.

Can anyone tell me what i can do? The ip address of my friend is 192.168.8.19 and the ip address of the adsl router is 192.168.0.1

I only want to allow that user to use the pppoe router.

thanx
