They have to be in the same subnet as both ISA uses the same Virtual IP address in NLB configuration. -----Original Message----- From: Paul Crisp [mailto:PCrisp@xxxxxxxxxxxxxxxxx] Sent: Friday, February 01, 2002 9:23 AM To: [ISAserver.org Discussion List] Subject: [isalist] RE: Cluster technologie ? http://www.ISAserver.org Unfortunately in my setup we have two offices connected via routers and a leased line, and 2 different subnets. Both offices have ISA servers, although 1 is for outgoing access and the other is primarily for incoming access, although can be used as a backup incase outgoing access server crashes.

The specific reason why I did not use arrays is because arrays require Firewall client software to be installed in all workstations. Arrays also make use of CARP for cache lookup, this is a plus. However, if you dont want to use FW client in all workstations, NLB is a good choice.

Any drawback to this compared to the NLB? -----Original Message----- From: Periyasamy, Raj [mailto:psraj@xxxxxxxxxxxx] Sent: Friday, February 01, 2002 9:10 AM To: [ISAserver.org Discussion List] Subject: [isalist] RE: Cluster technologie ? http://www.ISAserver.org It's a feature available in Advanced Server. I have two identical ISA servers. both are load balanced with NLB. Users access the ISA server using its virtual name. NLB server automatically divides the load between the 2 servers, and in case if one server fails, all users are moved to the surviving server.

Users are automatically moved to the other server in case if one fails. However, NLB does not provide fault tolerance for service failures. For this you may combine the Service recovery feature of Windows 2000 and NLB to achieve some level of fault tolerance and recovery.

The fact is that I want to my users not be deconnected if the ISA Server fall down !
