Fixed In:
13.0.0, 12.1.2

Opened: Oct 02, 2015
Severity: 3-Major

Symptoms

Some networking devices block a packet that has a TTL value higher than 230. The TTL value for the BIG-IP system is set to 255 internally and cannot be changed.

Impact

No access to the resources.

Conditions

The issue occurs when traffic originates from the BIG-IP system (as a client).

Workaround

None.

Fix Information

The TTL value can now be changed from the hardcoded value of 255. This supports the requirement that some networking devices have to block a packet whose TTL value is higher than 230.
