Able to connect to internet before PPPoE authentication

Sun Apr 20, 2014 12:40 am

Dear All,

I am at the very initial stage of learning Mikrotik. I just have setup PPPoE server on a Dell server and I connected my laptop directly to the LAN interface of the PPPoE server. I created a dialer on my machine, I was able to authenticate successfully. But I am not sure, I am able to connect to internet before PPPoE authentication. Can you please let me know why? Anything to do with firewall rules?

Thanks
Sibychan

Have configured an IP/dhcpserver on the ethernet interface of your PPPoE server?

This is because of default OPEN masquerade/nat rule you may have.
create a new ip pool in IP>POOL (Make sure its different then the dhcp pool, like for pppoe-pool you can use 172.16.1.1-172.16.1.255)

Now in the default NAT rule, in src addresss, add the pppoe client pool that is 172.16.1.1-172.16.1.255.
