Routing and Remote Access configuration
When you install ISA Server 2004, you can upgrade the Routing and Remote Access configuration. You can upgrade the configuration to ISA Server 2004, regardless of whether ISA Server 2000 is installed on the computer.
Note the following limitations to the Routing and Remote Access configuration upgrade:
- The maximum number of remote virtual private network (VPN) clients allowed to connect to ISA Server 2004 is set to whichever is larger on Routing and Remote Access: the number of PPTP ports or the number of L2TP ports. For more information, see Configure maximum number of simultaneous remote client connections.
- If the number of IP addresses statically assigned is smaller than the number of VPN clients, the number of VPN clients is reduced to fit the size of the static address pool. A warning is issued to the user during the Routing and Remote Access upgrade process.
- Preshared keys configured for Routing and Remote Access are not exported. A warning message is issued.
- If an invalid IP address is configured for the primary DNS server, it is not exported. The DHCP settings are used instead, and a warning message is issued. If an invalid IP address is configured for the backup DNS server, it is not exported. A warning message is issued.
- If an invalid IP address is configured for the primary WINS server, it is not exported. The DHCP settings are used instead, and a warning message is issued. If an invalid IP address is configured for the backup WINS server, it is not exported. A warning message is issued.
- If a site-to-site connection on Routing and Remote Access is configured as PPTP first (and then L2TP), it is upgraded to a remote site network on ISA Server 2004 that uses PPTP only. A warning message is issued.
- If a site-to-site connection on Routing and Remote Access is configured as L2TP first (and then PPTP), it is upgraded to a remote site network on ISA Server 2004 that uses L2TP only. A warning message is issued.
- Preshared keys configured for site-to-site connections in Routing and Remote Access are not exported. A warning message is issued.
- Credentials configured for site-to-site connections in Routing and Remote Access are not exported. On ISA Server 2004, outgoing VPN connections are disabled until you reconfigure them. A warning message is issued.
