Hello; I am a pilot and my airpark has asked me to create isolated LANs in each person's hangar. Then they want each person's LAN to be able to get to the Internet but not to be able to exchange data with any other LAN device - only their own. The Internet connection is cable and there is one LinkSys router in the main office supplying Internet access to the whole backbone. This backbone is a single piece of CAT5E that is run in to each hangar where a Netgear 10/100 5-port switch is located. Each hangar has their own switch. So in a sense, it's one big ethernet run on one big subnet. I want to place a wireless router in each hangar and keep each hangar on it's own subnet. Each subnet in each hangar must NOT be able to exchange data with any other LAN, but will need to be able to get to the Internet via the router in the main office. Will I have to use static routes to make this work? Suggestions on implementation? Thanks!
