dear all…
i just create pppoe server, and now it’s running.
majority my client use win xp, so they must create new network conection.
now if i want, the client isn’t must create new internet conection.. How that??
so client just get ip from my ip pool,if they will connect to internet, appear a pop up ask a username and password… Like in hotspot mikrotik…
please..help me… 
if you would like to create a hotspot you can use winbox to setup.
click ip->hotspot->setup
select interface you would like hotspot on → next
ip address of hotspot (should automatically come up with one)->next
IP pool for hotspot (also should automatically have one)->next
Select Certificate - choose none → next
IP address of SMTP server (not required) → next
DNS server addresses → next
DNS name - choose one like yourisp.lan → next
Create user for hotspot → next
finish.
your hotspot should now be setup, and any internet requests on that interface withou pppoe dialin will triger a redirect to the hotspot login page. where user can input thier username and password to access internet.
To add users without using userman
goto → ip → hotspot → users → click [+]
the rest should be simple.
for userman setup, follow wiki example
