Opened: Aug 10, 2017
Severity: 3-Major

Symptoms

A wrong source MAC address may be used in the outgoing IPsec encapsulated packets when the BIG-IP VE system is operated in Azure.

Impact

The Azure environment or a remote device may drop the outgoing IPsec encapsulated packets from the BIG-IP system because the source MAC address of the packets is wrong.

Conditions

The BIG-IP VE system is first deployed in Azure with a single NIC. After the first reboot and then power off, a second NIC is added to the BIG-IP system. Then, an IPsec tunnel is configured to associate with a selfip on the second NIC.

Workaround

None

Fix Information

The source MAC address of the outgoing IPsec encapsulated packets from the BIG-IP system is set correctly.
