CGNAT translations fail with the error message 'LSN Pick took too long'. The error message can be observed in logs or with the command 'tmsh show ltm lsn-pool failure-cause'.
Some outbound translations are rejected.
-- VIPRION 4450N blades when using default dag (net vlan cmp-hash default). -- FastL4 is configured -- Intra-chassis connection mirroring is configured.
You can use any of the following workarounds: -- Use SP Dag (net vlan cmp-hash src-ip/dst-ip). -- Disable connection mirroring. -- Configure a profile on the virtual server that is not FastL4.
Translation attempts no longer fail in this configuration.
