I am planning to add a guest SSID to my wireless network. I currently have AP-1231g access points configured as wpa using private certificates and a RADIUS server for authentication. I have added the guest SSID and created a vlan for it. What I am trying to figure out is the best solution for DHCP. Currently my private network uses a Microsoft server for dhcp. Unfortunately I cannot re-number my LAN to carve out a subnet for my guest users. I do not want them to be able to browse my internal network nor do I wish to enter static addresses for them. My edge firewall is a Cisco ASA5550 and I have an open port there. Would it be possible to enable dhcp on that interface and assign it to the same vlan as the guest SSID? Would I encounter issues with the access points and two different dhcp servers?
