To reproduce the bug use non exists pool for the translation rules
set nat cgnat pool external ext-01 external-port-range '1024-65535' set nat cgnat pool external ext-01 per-user-limit port '2000' set nat cgnat pool external ext-01 range 192.168.122.222/32 set nat cgnat pool internal int-01 range '100.64.0.0/28' set nat cgnat rule 10 source pool 'fake-pool' set nat cgnat rule 10 translation pool 'ext-01'
