salt.states.nftables¶

Management of nftables¶

This is an nftables-specific module designed to manage Linux firewalls. It is expected that this state module, and other system-specific firewall states, may at some point be deprecated in favor of a more generic firewall state.

salt.states.nftables.append(name, family='ipv4', **kwargs)¶

New in version 0.17.0.

Append a rule to a chain

name: A user-defined name to call this rule by in another part of a state or formula. This should not be an actual rule.
family: Network family, ipv4 or ipv6.

All other arguments are passed in with the same name as the long option that would normally be used for nftables, with one exception: --state is specified as connstate instead of state (not to be confused with ctstate).

salt.states.nftables.chain_absent(name, table='filter', family='ipv4')¶

New in version 2014.7.0.

Verify the chain is absent.

family: Networking family, either ipv4 or ipv6

salt.states.nftables.chain_present(name, table='filter', table_type=None, hook=None, priority=None, family='ipv4')¶

New in version 2014.7.0.

Changed in version 3002.

Verify a chain exists in a table.

name: A user-defined chain name.
table: The table to own the chain.
family: Networking family, either ipv4 or ipv6

salt.states.nftables.delete(name, family='ipv4', **kwargs)¶

New in version 2014.7.0.

Delete a rule to a chain

name: A user-defined name to call this rule by in another part of a state or formula. This should not be an actual rule.
family: Networking family, either ipv4 or ipv6

salt.states.nftables.flush(name, family='ipv4', ignore_absence=False, **kwargs)¶

New in version 2014.7.0.

Changed in version 3002.

Flush current nftables state

family: Networking family, either ipv4 or ipv6
ignore_absence: If set to True, attempts to flush a non-existent table will not result in a failed state.

New in version 3002.

salt.states.nftables.insert(name, family='ipv4', **kwargs)¶

New in version 2014.7.0.

Insert a rule into a chain

name: A user-defined name to call this rule by in another part of a state or formula. This should not be an actual rule.
family: Networking family, either ipv4 or ipv6

salt.states.nftables.set_policy(name, table='filter', family='ipv4', **kwargs)¶

New in version 3002.

Sets the default policy for nftables chains

table: The table that owns the chain that should be modified
family: Networking family, either ipv4 or ipv6
policy: The requested table policy (accept or drop)
save: Boolean to save the in-memory nftables settings to a file.
save_filename: The filename to save the nftables settings (default: /etc/nftables or /etc/nftables/salt-all-in-one.nft if the former is a directory)

salt.states.nftables.table_absent(name, family='ipv4', **kwargs)¶

New in version 3002.

Ensure an nftables table is absent

name: Name of the table to ensure is absent
family: Networking family, either ipv4 or ipv6

salt.states.nftables.table_present(name, family='ipv4', **kwargs)¶

New in version 3002.

Ensure an nftables table is present

name: A user-defined table name.
family: Networking family, either ipv4 or ipv6
