Services

Does Anyone know if there is a way to allow pass through to a whole network?  I have a public class B network x.x.0.0/16 that I would like to allow access to without the captive portal.  Anything else (the internet) would get a splash page.   The only thing I see here is individual addresses to use.   This of course works, however there will be a lot of work to add everything I need to add.

Any Ideas?


Thanks in advance
