WLC 2125 (running 5.2.193.0) - Trying to determine if it is possible to have a Guest SSID hand out an address from the internal DHCP server and have that NAT'd out a physically separate interface that just goes to a local ISP? Or is the only way to connect the separate port to a router/DHCP server for that network and let the external router do the NAT'ing?!?
