Upgrading ISA Server 2000 Network and Client Configuration Settings
ISA Server 2000 networks and client configuration settings are upgraded to ISA Server 2004, as detailed in the following sections.
Networks
ISA Server 2000 supports only two networks: internal and external. A perimeter network (DMZ) could be implied by creating packet filters to route traffic from the external network to the perimeter network.
ISA Server 2004 supports multiple networks, while stingray can have many networks that are equivalent. The following networks are created by default on ISA Server 2004:
- Internal network, derived from the ISA Server 2000 Local Address Table (LAT)
- External network
- Local host
- VPN clients network
The migration tool creates the following network rules on ISA Server 2004:
- A network rule that defines a route relationship between Local Host and Internal network.
- A network rule that defines a route relationship between Perimeter network and External network.
- A network rule that defines a NAT relationship from Internal network to Perimeter network.
Client Settings
In ISA Server 2004, client settings are per network. ISA Server 2000 client settings are upgraded directly to the client settings on ISA Server 2004's Internal network.
As in ISA Server 2000, ISA Server 20004 firewall client application settings apply to all client requests. Firewall client application settings are upgraded directly to ISA Server 2004.
