Hello Guys,
The Network diagram on this url is exactly what i wannt to configure, but with some difference.
http://www.cisco.com/en/US/tech/tk389/tk390/technologies_configuration_example09186a00800949fd.shtml
At the moment wy have only Vlan 1 on the cat 3548xl and no trunking configure on between Router and Switch. all switch interfaces are on the Vlan1 and obtain thier Ip addresse from an DHCP (PC) Server also on the VLAN 1.
a) I wannt to create a new Vlan (Vlan2) for Wireless LAN and configure on the Router another DHCP Server to assign Ip Addresse only for Wireless users.
b) no connection between Both VLANs (not Ping) because Wireless Users are External Users, there will only need to get an Internet access no LAN Connectivity.
how can It configure this issue ? is possibleto configure it like this ?
do you have any better solution ?
Thanks for any help

sounds like you need to create a second vlan in the switch and make the uplink to the router a trunk. Connect the wireless access points to switch ports that you put into the new vlan. It also sounds like you want to run the router as a dhcp server for that vlan, that should work. Then you need access lists to block the wireless network from reaching the other interior network. However, you may need to open holes in the access list to let them reach dns or the dhcp server will have to feed them a dns they can reach on the internet. If you are planning authentication you will need to account for the location of the authentication host.
