52 Chapter 2 Getting started
Preparing for configuration
To properly prepare for configuration of the Nortel VPN Router, you should have
the following items available:
• A plan to distribute IP addresses to clients when connections are requested;
for example, via a DHCP server or an internal client address pool (with an
address pool you need a range of IP addresses).
• An Authentication database. If you are not using internal authentication via
the LDAP database, then make sure you have either the external LDAP or the
RADIUS server’s IP address and password or Shared Secret (password).
• An external accounting server, such as RADIUS, with its IP address and
Shared Secret (password).
• Prepare the clients for the type of tunneling protocol they need to use. The
PPTP client application is available on the Nortel CD for Windows 95, and it
comes with Windows 98 and Windows NT. Nortel also provides the IPsec
client on the Nortel CD.
You should develop a complete network topology (physical and logical) of the
environment in which you are testing the Nortel VPN Router. This should include
the following: •
• Details of physical communication links, such as cable length, grade, and
approximation of the physical paths of the wiring, analog, fiber and ISDN
lines.
• Nortel VPN Router and router types.
• Servers, with computer name, IP address (if static), server role, and domain
membership.
• Location of devices such as printers, hubs, Nortel VPN Routers, modems,
routers, bridges, proxy servers and firewalls (intranet & Internet) on the
network.
• WAN communication links (analog / ISDN / ATM) and the available
bandwidth between sites, either an approximation or the actual measured
capacity.
• Number of users at each site, including mobile users.
