SMTP and VNC access without radius login
Actually after posting several posts without an answer in chillispot and openwrt forums, I am putting my problems here. Please consider it.
I am using openwrt with chillispot in linksys wrt54gl. My radius server is freeradius. When I start web browser, it is directed to login page and after entering username and password(login) only I can surf web.
But my problem is, without login also, I can send and receive email in microsoft outlook. It is using smtp (my workplace internal mail). Even without login I can use vnc and connect to remote server. I want to block it and user should only access outlook mails and vnc only after successful login.
It must be the problem with iptables. I am using iptables given by chillispot (firewall.openwrt).
Please help me!!
