I've intalled a little LAN at home.
Modem/Router Digicom Wave 125 (4 eth switch, Firewall, Diect connection to ADSL 4 MB)
PC1 - AMD Athlon 4800+ with Windows XP SP2 + Printer Canon MP600
PC2 - Intel P4 2.0 Ghz with Windows XP SP2
PC3 - Intel Pentium II 400 Mhz with Windows 98 snd edition.
All PC's are in the same WorkGroup named HOME and are sharing Internet connection, files, directories and the Printer without any password to be introduced. We only switch on the computers and start working or surfing on Internet.
Everything goes OK.
I want now to offer (i've a B&B) Internet connectivity, thoughout WI-FI, to Guest that occasionally ask for the service.
I want, therefore protect my LAN from intrusion from the guest with a simple solution that doesn't give me some extrawork or extra password insertion when the Guest are not at my home.
I knows that there is a lot of possibilities but, how I can handle the situation in the maximum semplicity and without modifiing the infrastructure everytime that I receive a Guest?
