I have no knowledge of the ruckus system and how it works, but ideally the access points should not be accessible from the 192.168.182.0/24 network due to security concerns and the limited number of addresses available imposing an upper bound to the number of access points and users that can be supported. All addresses in this network apart from 192.168.182.1/255 should be used by clients. The limiting factor in this instance would appear to be your ruckus gear firewalling this ip range used by chillispot. You will need to contact ruckus-knowledgeable people to find out if and how to alter the ruckus setup to allow the ip range through the APs onto the LAN.
Regarding your question of “how do you split the ports on the router”, if you have your wrt54g running dd-wrt or openwrt then the matter is as simple as using the inbuilt vlan technology of the broadcom chipset which is supported by both of these OS. NOTE: there are two methods of vlans using broadcom, being port-based and 802.1q-based. If your ruckus gear can use 802.1q vlans and you insist on the equipment being on the same segment as your clients then you can use this method. However, the alternative, port-based vlans, does not require the additional implementation requirement on connected equipment, and therefore is easier to setup. Port-based essentially removes one or more of the LAN ports from the switching hub on your wrt54g router and designates it/them as a separate network segment allowing for multiple IP ranges to be utilised by the router on the various LAN ports without requiring 802.1q.
I hope you find some of this information helpful, and I am sorry I can’t help more with your main problem between the ruckus ap(s) and chillispot, which I would guess is down to an inbuilt firewalling mechanism in the APs.
