Fixed In:

Opened: Dec 08, 2014

Severity: 3-Major

Symptoms

If a client machine uses proxy and Network Access does not specify any proxy, then Safari should not use proxy for some Network Access resource after the Network Access tunnel is created. However, Safari does so. This problem occurs with Safari 8. Other versions of Safari and other browsers work as expected in our testing. Apple has been notified: rdar://problem/18651124

Impact

As a result, some Network Access resource might be unavailable.

Conditions

The problem occurs when all of these conditions exist: 1. OS = Mac OS X Yosemite. 2. Configuration = Client machine has local proxy configured and Network Access on BIG-IP system access policy does not specify any proxy. 3. Action = Accessing Network Access resource after tunnel is created.

Workaround

There is no workaround at this time.

Fix Information
