Sending firewall logs to remote syslog on non-standard port

I setup a Nagios Log server on my network and want to configure my edgemax router to send it's logs to said server. The issue is that the Nagios listens on port 5544 and not 514.

Where on the edgemax do I change the port that it sends traffic to. On the system tab in the syslog box I tried putting 192.168.x.x:5544 but that did not work.
