Hi guys, I am sure someone has been faced with this problem, and I was just wondering what the possible solutions are. A city wide free wireless network has just expanded to cover the area encompassing our building. The provider of this is also the provider of our Internet (via fiber). It was decided that it would be advantageous for some of our employees to be able to use this wireless network when we bring in clients etc. This of course opens a large possibility of problems concerning crap getting onto our network (especially if they are connected to wireless and plugged into the network). We have made it a policy that a personal firewall be installed on all firewalls, and that at no time is a wireless card to be plugged into a laptop while connected to our LAN. This of course does not do much for internal cards .... Is there anyway at all that I can firewall this ? Or is there a way o prevent the two networks from being active at the same time .. I am at a bit of a loss here. Thank you all, Peter Peter Marshall, BCS Network Administrator, CARIS 115 Waggoners Lane, Fredericton NB, E3B 2L4 CANADA Phone: (506) 458-8533 (Reception)
