I'm told, that some hotspots works fine, even when the visitor has setup a static IP in their network settings, and this IP/netmask is "wrong" (for the current hotspot). The hotspot does some tricky routing, so everyone (with all setups, different static IPs/netmasks) can use the network. How is this done? I'm setting up a network, that will be used by many people (and many of these don't have any clue of how to change the settings on their PCs) - so I wan't everything to work - out of the box - also if their configuration is "wrong". I hope you understand what I mean.
