Can i forward all the traffic to a specific website?

Dear all,

I am setting up a secure wlan network.

-802.1x on vlan 1

-wep on vlan 2

can I restrict/forward all the traffic from client in vlan 2 to a specific ip(website)? So that the client can read the instruction and get the cert for the

Is that possible and how can I deploy it?

BTW, how those public wlan hotspot do it? Is that a software from cisco can do the similar things? I heard that cisco do have... do I need to buy it?

thanks.

Regards, Louis
