Still no answer from D-Link support!
Or the first aswer i got was, suggesting to setup a portforwarding rule... Ehhhh......
Then the ticket was closed so i reopened it, adding information that it's the router
that is supposed to send the syslog messages to a pinpointed syslog server in the network!
But there is no menu option available in the menu to specify the IP address of your syslog server.
Still it's supposed to be able to do so according to the manual and available web info about the product,
so it should ned to be escalated or addressed to the engineering team to add it in a future firmware release. Or the manual and available product information has to be changed!
I think the old DGL-4300 had this option if they wonder what we are talking about!
If you have the need for this, my suggestion is that you do open a support ticket for the problem and ask them to correct this problem in the router firmware....
