A couple of options come to mind... - Create a separate subnet to dish out IPs in a different range, and filter via subnet. - Give reservations to all of your "known" computers, and leave the rest open in DHCP, then filter by IP range. -----Original Message----- From: Ted D [mailto:tdoholis@xxxxxxxxxxxxx] Sent: Thursday, April 28, 2005 16:44 To: [ISAserver.org Discussion List] Subject: [isalist] Occasional visitors http://www.ISAserver.org Hi All, I'm wondering what you do in the following situation: I have about 10 people per week that come to our office from other companies and while here, require internet access. Currently I allow authenticated connections only to the internet. For the regulars, I record the mac address and create a DHCP reservation for them and then allow that range anonymously to the net but this is becomming cumbersome. Thanks for the input. TD
