allowed-ips

List of IP addresses that are allowed to send syslog messages to the server (one per element).

Note

It is necessary to allow at least one IP address when using the syslog connection type.

deny-ips

List of IP addresses that are not allowed to send syslog messages to the server(one per element).

Allowed: Any IP address or network

local_ip

Local ip address to listen for connections.

Default: all interfaces

Allowed: Any internal ip address

Note

This is not well tested. For the time being I recommend using the full IPv6 address instead of one of the many shortcuts.
