Basically right now i have several 1252's running on a facility wide Vlan, meaning the same vlan subnet as all other users, problem is internet is filtered by an iprism web filter.  These access points are basically for guest internet access for the most part.  So they are being filter,  What i was thinking of doing was putting them in their own vlan, one of the questions i have is about clients getting addressing.  Should i set up the access points to hand out addresses for that subnet, or use an existing dhcp server and set up a new scope? If i do it that way, how do i specify that dhcp server as a helper?

thanks

The second VLAN will likely have a different IP scheme.  You can setup a second scope on your current DHCP server if it can see both VLANs. (Physically connected to both VLANs).  It would not be a helper, it would be the DHCP server for that network.

Your router will need to handle the seperate VLAN access to the Internet etc.

Depending on your router model, it may be able to do the dhcp scope for the VLAN.

its a 2821 and they can see the other vlans, they are all connected via fiber to a main resource center where the router is housed.  my goal is to create that separate vlan and just put a passall filter in the iprism for that vlan to allow it somewhat unrestricted access to the internet... so basically say i create a vlan on the router for 10.10.150  ill just statically assign the aironets to use ,1 for the gateway while giving them an IP on that subnet, and just drop the switchports on the dell 6248 into that vlan and create and additional scope on the dhcp server and i should be good to go then?

Yes, as long as the DHCP server can see the VLAN with the 10.10.150.x network you should be ok.

Make sure the router vlan interface is 10.10.150.1 too :)
