[solved]internet running with hotspot user, but offline using radius user

Guys, i need a enlightenment.
I completed the setup hotspot and radius using RB750 firmware 6.

  • done create user in hostpot & radius
  • done create profile in usermanager
  • Test ping and DNS in mikrotik smoothly
  • when hotspot user login with internet smoothly

But the problem occurs when the user login with radius. Login smooth with a login status, but can not access the internet. web pages keep loading until send message in browser “There is no Internet connection”.
i have folow step in here http://forum.mikrotik.com/t/internet-not-working-after-hotspot-setup/75701/1 but seems no luck.
Thanks before bro
