IPCOP Firewall Install and Config

I have a hotel on an island in Costa Rica. We have a 10 meg connection coming via microwaves from the mainland. I have a server here with 3 ethernet ports. We have a network OF ubiquity indoor and outdoor access points. I would like to use the server to bring in the 10 megas from the dish and dedicate 2 megs out of one ethernet port for dedicated office and company use and send the remaining 8 megs to the guest network. I want a firewall set up so that: 1 ) the guest has to accept terms and signs onto the network via a webpage so no password is needed (similar to free airport wifi) 2 ) We can ban employee devices preventing them from accessing hotel WIFI 3) Provide an internal network website for concierge service.
