How to forward Syslog UDP port 514 to LOGalyze

NOTE: The instructions in this section assume that your firewall is enabled and is compatible with iptables.

LOGalyze usually runs as logalyze user, therefor it cannot directly listen on ports that are lower than 1024. To listen on a port that is lower than 1024, use port forwarding to forward data to a port that LOGalyze can directly listen on. Default syslog collector port is 1670.

You must run the following port forwarding command as root.

iptables -t nat -A PREROUTING -p udp --destination-port 514 -j REDIRECT --to-ports 1670
