Chapter 4: Configuring Cisco VPN 3000 for Remote Access Using Preshared Keys

following is a list of the data values you need to obtain to completely conﬁgure your Cisco VPN

3000 Series Concentrator:

•

Private interface IP address, subnet mask, speed, and duplex mode.

•

Public interface IP address, subnet mask, speed, and duplex mode.

•

VPN concentrator’s device or system name.

•

System date and time of day.

• VPN tunnel protocol that you will use, either IPSec, PPTP, or L2TP.

• Your local DNS server’s IP address.

• Your registered domain name.

• The IP address or host name for the concentrator’s default gateway.

• (Optional) Additional interfaces (for example, for a DMZ, on models 3015–3080 only),

IP addresses, subnet masks, speed, and duplex mode.

• (Optional) IP address or host name of your DHCP server, if your concentrator will be

using DHCP to assign addresses to remote users.

• (Optional) A pool of IP addresses if the VPN concentrator will be assigning addresses to

remote users.

• (Optional) For external RADIUS user authentication, the IP address or host name, port

number, and server secret or password for the RADIUS server.

• (Optional) For external Windows NT Domain user authentication, the IP address, port

number, and Primary Domain Controller (PDC) host name for your domain.

• (Optional) For external SDI user authentication, the IP address and port number for the

SDI server.

• (Optional) For internal VPN concentrator user authentication, the username and password

for each user. If you specify per-user address assignment, you also need the IP address and

subnet mask for each user.

• (Optional) For the IPSec tunneling protocol, a name and password for the IPSec tunnel

group.

Cisco VPN 3000 Concentrator Initial Conﬁguration

When the Cisco VPN 3000 Concentrator is powered on for the ﬁrst time, it boots up the factory

default conﬁguration, which offers a Quick Conﬁguration option. The data requested by the

Quick Conﬁguration mode are enough to make the concentrator operational. Once you have the

basic conﬁguration entered through this mode, you can ﬁne-tune the conﬁguration through

normal menu options.
