Ayn and Leo, many thanks for your help.
As suggested by Leo, I used the "Send to this Syslog server IP address" option on the Netgear router and entered my main computer's IP address (192.168.0.2). I run the Splunk server on this computer.
When I then tried to set-up a new UDP data input, Splunk returned “Encountered the following error while trying to save: In handler 'udp': UDP port 514 is not available”. I was able to solve this thanks to gabedimeglio’s answer to: http://answers.splunk.com/questions/1653/cant-add-udp-input-because-of-error-udp-port-514-is-not-available-why. The key was to use “sudo ./splunk start” rather than just “./splunk start”.
I can now see the router’s syslog events in splunk>Search so it seems that I am all set now.
Thanks again (and to gabedimelio too)!
