Hi everyone. I'm about to embark on a project with wireless lans and trying to make them a little more secure. Not so much the 802.11 protocol itself , but I would like to the wireless people from accessing everyone else on the network, and just be able to get right out to the Internet. IF the people on the wireless lan need to access resources on one of the machines that is "wired", then I would like to use something like PPTP so I can force encryption and authentication for access to that information. My first question is, if I add an interface to my ISA server and make it just for the Wireless Access Points, can ISA keep it separate from everyone else, so that they can not view that network at all? Second, and this is just a theory question since I have not tried this yet, but would setting up ISA to allow PPTP/VPN through the different internal networks be the same as setting it up to allow someone on the Internet to VPN in to a private network? Does anyone else have any other ideas to try to keep it secure? My main mission is to keep people who don't belong on the network (like some guy driving down the street with his laptop on) from getting access to more secure parts of the network (where the data servers are). Thanks in advance, --Brian
