Connect wireless connection to Class B network

We previously had a class C network.  Were running out of IP's.

Now have a class B network, with Cisco 5510 connected to DSL and Cisco 50x connected to cable.  DHCP provided by netware server.  Previously, with Class C address, we had a Linksys wireless access point connected to the network to provide internet access for outside board of directors.

We currently have available Linksys router from old Class C network that connected to cable modem.

DSL - Cisco 5510 - 172.16.0.1, 255.255.0.0  Iprism network access device protects this device
Cable - Cisco 50x - 172.16.1.3 255.255.0.0

We would like to use the Linksys wireless access point to connect to the linkysys router to go over the 172.16.1.3 gateway.  It would be ideal to have DHCP provided by the Linksys router only to wireless users using Class C Address and go directly to the 172.16.1.3 gateway without access to any of the Class B network addresses other than the 172.16.1.3 gateway.  Is this possible and how do you configure the Linksys router.

I was not using the Wan port and tried to configure an older Linksys router, setting in router versus gateway mode and could not get it to work properly.

Thanks.

I have a similar situation except I have 1 boadband line and 6 ip address
I have one Ip address on pix 506e for primary network and one ip on 3com router for pc lab.
I added buffalo wireless router to 3com for public wirelss ap but I too wanted it on seperate network.
Run cable from lan port on router to wan on linksys
Set linksys router to dhcp on wan interface or you can add static ip on wan inside the 172.16.1 network.
Set linksys as dhcp router to lan clients and use default 192.168.1.x range.

Wireless encryption, ssid and such is up to you but this should take care of what you need.
