Ok this is just a rough sketch of what I plan to set up, but I'm not sure if it will work or if its been done before.
Im looking at setting up a firewall for my office. right now we are using IPCOP, but i'ld like a little bit more control (plus if you build it your self you get a better idea of what your working with). Anyhow enough of my rambling:
I want to set it up with 4 nics
1 red zone - for the outside world
1 DMZ - mail servers and what not
1 blue zone - for wifi access
1 green - local trusted zone
I know the red green and DMZ are relatively easy to set up using IPTables, but I havent found any real info on setting up the blue zone.
My idea was to set it up like another dmz only have NoCatAuth set up as the captive portal to keep access control. Once the user authenticates they would have access to the outside world through the firewall (still have to protect the execs windows lappies from the windows vuln of the week) and only allow access to the green zone via VPN.
If I am not chasing windmills (been know to do so), I think it can be done... I know some of the firewall distro's are working on it (wifi zone) but I have yet to see anything. So any comments are welcome, feel free to call me a raving lunatic (I may just be).
Also if anyone knows of any good IPTables references please let me know.
Im just starting on this project and would like to know if I sitting the right way on the horse before I go chasing windmills.... er... monsters
