Severity: 3-Major


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 virtual server.


Server-side IPV4 packets are forwarded with destination address modified. The server side packets will not reach the intended destination, resulting in connection failures.


-- Create iRules for LTM pool selection. -- Configure the Virtual Server with "translate-address disabled". -- Send IPV6 client request hitting the NAT64 virtual


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