FVS318v3 Scenario 2: FVS318v3 to FVS318v3 with RSA

Certificates

The following is a typical gateway-to-gateway VPN that uses Public Key Infrastructure x.509
(PKIX) certificates for authentication. The network setup is identical to the one given in
Scenario 1. The IKE Phase 1 and Phase 2 parameters are identical to the ones given in Scenario 1,
with the exception that the identification is done with signatures authenticated by PKIX
certificates.
Note: Before completing this configuration scenario, make sure the correct T ime Zone is set on the
FVS318v3. For instructions on this topic, see “Time Zone” on page 4-13.
1. Obtain a root certificate.
a. Obtain the root certificate (that includes the public key) from a Certificate Authority (CA)
Note: The procedure for obtaining certificates differs from a CA like Verisign and a CA
such as a Windows 2000 certificate server, which an organization operates for providing
certificates for its members. For example, an administrator of a Windows 2000 certificate
server might provide it to you via e-mail.
b. Save the certificate as a text file called trust.txt.
2. Install the trusted CA certificate for the Trusted Root CA.
a. Log in to the FVS318v3.
b. From the main menu VPN section, click the CAs link.
c. Click Add to add a CA.
d. Click Browse to locate the trust.txt file.
e. Click Upload.
3. Create a certificate request for the FVS318v3.
