Ip Address Types - Nortel NN46120-104 User Manual

IP Address Types

When configuring the VPN Gateway you will come across quite a number
of IP address types. Following are the most commonly used:
Host IP Address
Each VPN Gateway can be assigned one or several host (machine) IP
addresses for network connectivity. You will be asked to enter a host IP
address when performing the initial setup.
Management IP Address (MIP)
When you create a new cluster you will be prompted for a Management
IP (MIP) address, which is an IP alias to one of the VPN Gateways in
the cluster. The MIP address identifies the cluster and is used when
making configuration changes through Telnet or SSH or when configuring
the system using the Browser-Based Management Interface (BBI). The
MIP always resides on a master VPN Gateway. If the master NVG that
currently holds the MIP should fail, the MIP automatically migrates to a
functional master NVG.
Virtual IP Address (VIP)
When the VPN Gateway is used in conjunction with a Nortel Application
Switch, e.g. for SSL acceleration, the client connects to the VIP on the
Nortel Application Switch. The VIP is used by the Nortel Application Switch
to load balance particular service requests (like HTTP) to other servers.
Portal IP Address
When the VPN Gateway is used to set up a web Portal, the Portal IP
address is the address that is assigned to the VPN Gateway's portal
server. To display the web Portal, the remote user should enter the Portal
IP address or the corresponding domain name in the available browser.
Real Server IP Address (RIP)
When the VPN Gateway is used for SSL Acceleration, the RIP is the
IP address of the real server, sometimes called the backend server. It
is the IP address that the Nortel Application Switch load balances to
when requests are made to a virtual server IP address (VIP). The VPN
Gateway's host IP address will in fact be one of the switch's RIPs.
