Hi Bjørnar, ISA Server only see trusted (LAT) zones and untrusted (non-LAT) zones. However, you can put mutiple network interfaces connected to LAT segments and use RRAS packet filter to prevent the networks from communicating with one another. You can also use IPSec Policies to further enhance this.

I have a small customer with one ISA server. They have two seperate departments located at the same place. They should not have access to each other, but both need internet access. Can I do this with several nettwork cards on one ISA. With larger customers, we sometimes need a lot of segments, and would need even more inernal zones - do ISA support this? ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Exchange Server Resource Site: http://www.msexchange.org/ Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
