In 1.5-rolling-202502030007, if the global state-policy for invalid packets is set to reject, a error is produced:
vyos@host# set firewall global-options state-policy invalid action Possible completions: accept Action to accept drop Action to drop reject Action to reject [edit] vyos@host# set firewall global-options state-policy invalid action reject [edit] vyos@host# commit [ firewall ] Failed to apply firewall: /run/nftables.conf:2234:9-39: Error: Could not process rule: Operation not supported ct state invalid counter reject ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ /run/nftables.conf:2235:9-39: Error: Could not process rule: Operation not supported ct state related counter accept ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ /run/nftables.conf:2236:9-14: Error: Could not process rule: Operation not supported return ^^^^^^ [[firewall]] failed Commit failed
This worked in an older version (for ex. 1.5-rolling-202406060020) and the completion shows it as a valid option.
The actions "drop" and "accept" still work fine.
