Which ports should be opened/forwarded to allow external use of the ZULU calendar server. (version 1.018)
I've tried the apple default calDAV :8008 and webDAV :80
i can't see any of this in the documentation either.
Googling this only turns up port 8040 but that's the old plugin version right?

Sorry! solved it. We have another webserver in our subnet so I've forwarded :8080 to port 80 on the FM server.
