Symptoms

If the server certificate status is revoked, SSL forward proxy configured with a new server SSL profile might drop the connection.

Impact

BIG-IP client connections are reset.

Conditions

-- New SSL forward proxy server SSL profile is attached to the virtual server. -- Revoked-cert-status-response-control is set to the default value (drop). -- Certificate status service (e.g., CRL/OCSP) is configured on the server SSL profile.

Workaround

Change revoked-cert-status-response-control to ignore on the server SSL profile.

Fix Information

If ssl-forward-proxy is enabled for new server SSL profiles, and revoked-cert-status-response-control is not specified, it will automatically be set to ignore. Client connection go through and the client will see a forged revoked certificate status.
