Cyber Security
VPN Client Advanced Configuration

This procedure describes the process of
creating the actual VPN IPSec. tunnel connection into the BNL campus
network.
For Client Versions:
- 363A-k9 (windows)
- 372-k9 (linux/solaris)
- 373A-k9 (apple)
From your PC desktop, double-click the Cisco VPN Client
application. This is the yellow lock shaped icon. If
you chose the default location for installation of the application,
it will be located in C:\Program Files\Cisco Systems\VPN
Client.
The VPN Client window will open.

When you initially start up the VPN Dialer, it should contain
pre-configured information in the Connection Entry and
Host name fields. If this information is blank (as shown above),
click New and fill in New Connection fields to match those shown in
the next four pictures.

Enter connection and description information as shown above and
click the Next button.

Enter the Fully Qualified DNS name of the VPN server
as shown above
(vpngateway.bnl.gov).
If you are using a network provider that does not support the DNS
service, the VPN gateway's IP address will also work. The VPN servers IP address
is (130.199.3.27).
Click the Next button to continue.

Using the information provided to you from the BNL
Account Management Office, Enter the VPN Group Name and the
common shared Password. Note that the Password will not be visible. You
must enter the same password twice to ensure a match. When done,
Click the Next pushbutton to continue.
- AGS CAD VPN Group - users who wish to access this group
should contact John Gould ( 631-344-3951 or
jgould@bnl.gov ) for Group
Access Information.

Click the Finish button to complete the New Connection setup.
Connecting to the BNL Pix VPN

Now that the Connection Entry has been created, Click Connect to
connect to BNL's Pix VPN.


Enter your Crypto-Card username in the top dialogue
box. Do not enter the Password at this time. Click the
OK pushbutton.

The VPN will now attempt to connect to the BNL VPN server using
your CRYPTOCard Username. This first attempt will fail since you did
not supply a password. This in turn forces the CRYPTOCard server to
display the CRYPTOCard Challenge to you (see above); this is helpful
if you need to re-sync
your CRYPTOCard token (by entering the displayed challenge into
your CRYPTOCard token). You can determine that your in sync by the
fact that the CryptoCard challenge (in the above window) will be the
same as that displayed on your soft token or on the hard card.
Now enter your CRYPTOCard Password Response in the Password field
above and click the OK button. In a few moments you should
have a secure connection status.
Note:
If you use a CRYPTOCard
software token, please be aware that when you start up your software
token, its application window and additional prompts may open up
directly behind the "User Authentication for BNL Pix VPN" window.
You may need to move the "User Authentication for BNL Pix VPN"
window in order to see your software token windows.
Notice the yellow "lock" icon on the right hand side of the task
bar. This is the visual indication that you have an encrypted VPN
link. You can right-click on this icon to determine
the status and performance characteristic of your VPN connection.

Caveats:
At this time, there have been minimal reports of problems using
this VPN service. One issue which has been reported a few times has
to due with home networks. If you use a LinkSys router, wireless or
not, make note of the local (internal) side of the router. If you
are using the default network of 192.168.1.0/24 as your home DHCP
network, you will have problems using the BNL perimeter proxies from
the VPN tunnel. Since the internal BNL proxies are located on the
same IP network as your home network, you will not be able to access
non-BNL sites via the VPN tunnel unless you re-configure you LinkSys
router to be on a different local network. The simplest solution is
to assign you home network to be on the 192.168.254.0/24 network or
on the 10.0.0.0 network. This configuration change will allow you to
use all of the BNL campus network resources without any problem.
