Configuration Examples for SSL Termination and Proxy Modes

Configuration Examples for SSL Termination and Proxy Modes
This section describes the procedures required to perform the configurations described in “SSL
Termination Mode” on page 137 and “SSL Proxy Mode” on page 138. As shown in the examples
there, SSL Termination mode provides for an SSL connection between clients to the ServerIron
ADX. When configuring SSL Proxy Mode a configuration is created between the ServerIron ADX and
the server. In this case, the ServerIron ADX is configured as a client to the server.
Configuring SSL Termination Mode
In this mode, for enabling VRRPE for VIP address, it is necessary to use a different source-nat-ip for
ssl traffic.
For performing this function, use the following syntax:
Syntax: server source-nat-ip <ip> <mask> <gateway> port-range <range>
To configure SSL in the termination mode, perform the following tasks in sequence:
1. Generate or obtain an RSA key pair and copy it to the ServerIron ADX
2. Obtain a digital certificate and copy it to the ServerIron ADX
3. Create an SSL profile as described in “Allowing Self Signed Certificates” on page 169
4. Within the SSL profile specify a keypair file as described in “Specifying a keypair file” on
page 165.
5. Within the SSL profile specify a digital certificate file as described in “Specifying a certificate
file” on page 166.
6. Within the SSL profile select a Cipher Suite as described in “Specifying a cipher suite” on
page 165. This is optional.
7. Configure Real and Virtual Servers as described in “Configuring Real and Virtual Servers for
SSL Termination Mode” on page 173
Example
Generate an RSA key pair
ServerIronADX# ssl genrsa rsakey-file 1024 mypassword
Generate a Self-signed Digital Certificate
ServerIronADX# ssl gencert certkey rsakey-file signkey rsakey-file mypassword
mycert
