Opened: Aug 06, 2019
Severity: 3-Major

Symptoms

IPv4 Packets are forwarded to server-side with destination address changed to LTM pool member address even when 'translate-address disabled' is configured on a NAT64 virtual server.

Impact

Server-side IPv4 packets are forwarded with destination address modified. The server-side packets do not reach the intended destination, resulting in connection failures.

Conditions

-- Create iRules for LTM pool selection. -- Configure the NAT64 virtual server with 'translate-address disabled'. -- Send IPv6 client request accessing the NAT64 virtual server.

Workaround

Use normal LTM pool selection instead of iRules-based, LTM pool selection.

Fix Information

None
