You have decisions to make. Is the corporate DHCP your only DHCP provider or will you have the wireless router provide DHCP? Will you use NAT on the wireless router? Does the wireless router have a firewall and will you manage it?
My suggestion is to disable DHCP, NAT and the firewall on the wireless router (turning it basically into a wireless AP). Then manage IP addresses through your central DHCP.
Otherwise carve out an IP segment for the wireless router separate from your central DHCP and assign that as the DHCP pool on the wireless router.
The decision on NAT is up to you but if you need to access network resources from the wireless segment turning off NAT is a no brainer.
Using the wireless router’s firewall inside your network in a hassle you probably will not want. My suggestion is to turn it off.
