Figure 4.44 shows the state of the /config/bigip.conf file, after both creating
an SSL proxy with SSL-to-Server enabled and configuring the certificates
and keys for both client-side and server-side SSL connections.
Configuring server certificate authentication
You can verify server certificates, as well as specify the maximum number
of certificates to be traversed in a server certificate chain.
Tip
In addition to configuring certificate authentication, you must also
configure the trusted CAs. For more information, see Specifying a list of
trusted Certificate Authorities (CAs), on page 4-102.
Verifying server certificates
To implement certificate authentication on the server side (that is, between
the SSL proxy and the server), you can configure the proxy to either require
the server to present a certificate or ignore the presentation of a certificate.
Note, however, that you cannot require the server to present a certificate if
anonymous cipher suites are negotiated.
If this option is set to require (the default setting), the proxy verifies any
certificate presented by the server. If this verification fails, the SSL
connection also fails, and the corresponding client connection is closed. If
this option is set to ignore, verification fails only when a certificate is
presented by the server and the certificate is expired or malformed.
To verify server certificates using the Configuration utility
1. From navigation pane, click Proxies.
2. Click the Add button.
3. In the Server Certificate field, select require or ignore from the
box.
4. Click Done.
