i can try and test this out myself, yet thought would ask if someone knows regarding logging to remote PC/server (across internet) using ddns alias and not IP for syslog in obi ..?
EDIT: Obi support got back to me saying
"
Please continue to use IP address for syslog server.
We don't do DNS lookup for "Syslog Server"
"
So IP address works and not any 'host name'..
