I have heard that it exists somes professionnals products that are able to
manage on a captive portail With not only dhcp but any hosts without any
modification of the tcp configuration.

This solutions are able to detect all the broadcast on the lan and create a
dynamic virtual gateway to capture them on the portail.

They speek of the bbsm of cisco ?

What do you think of this solution (that I found very cool ) and will
monowall get this idea ?
