Chapter 14: Configuring Virtual Private Networks Example VPN Scenarios 460 d On the Advanced tab: No changes needed e Click Add to save the new VPN association. f Click the Save icon to save your changes. 4 In the Admin Console, Services Configuration > Certificate Management. On the Remote Certificates tab click New and create a certificate for a client by specifying the following: Note: You can skip this step and step 5 for those clients that have online access to the CA. These clients can create and retrieve their own certificates. • Certificate Name = Sales_A • Distinguished Name: CN=Sales_A,OU=sales,O=bizco,C=US • Submit to CA = BizcoCA • Signature Type = RSA • Private Key: Click Browse and specify where you want to save the private key associated with this certificate. In this scenario it is common to save the certificate to the same location as the exported firewall certificate. • Certificate: Click Browse and specify where you want to save this certificate. In this scenario it is common to save the certificate to the same location as the private key and the exported firewall certificate. • Click Add. • Click the Save icon to save your changes. 5 In the Admin Console, Services Configuration > Certificate Management. Export the CA certificate and the firewall certificate to the same location used in step 4. a On the Certificate Authorities tab, select the CA certificate you created in step 1A, then click Export and export the certificate by specifying the following: • Destination = File • Generated CA Certificate File: Click Browse and specify where you want to save the CA certificate. Add the .pem extension to the file name. • Click OK. b [Optional] On the Firewall Certificates tab, select the firewall certificate you created in step 1B, then click Export and export the certificate by specifying the following: • Destination = File • Export Firewall Certificate to File: Click Browse and specify where you want to save the firewall certificate. Add the .pem extension to the file name. • Click OK. 6 Repeat steps 4 and 5 for each remote client.
Chapter 14: Configuring Virtual Private Networks Example VPN Scenarios When you are finished your storage location should have four items for each remote client: the CA certificate, the firewall certificate, the unique private key for the client, and the remote certificate for the client. Summary Sidewinder G2 is ready to accept connections across this VPN as soon as the remote clients are configured. In order to configure their end of the VPN connection, each client will need the client-specific certificate and private key information you saved in step 4 as well as the firewall and CA certificates created in step 5. If you saved this information to diskette you can either distribute the information in person or mail it to them, or perform the imports while the machine is within a trusted network. It is not safe to distribute certificate and private key information via e-mail. Note: The configuration described above restricts VPN traffic by terminating the VPN association in a virtual burb. Proxies and rules must be configured to specify what access the VPN clients have to the trusted network. 461
