I would leave the core in DHCP mode. If you want to make sure it keeps the address make a reservation in the router. More importantly have you done the port forwarding? 192.168. 28.35 and port 55002
It was helpful fellow Roon user @Bernd_Kurte who provided the assistance here, so thank you @Bernd_Kurte for volunteering your time and expertise.
@Nikolay_Frolov, an alternative to setting the manual port forwarding rule in the video above is to enable UPnP on your router; the diagnostics you’ve provided suggest that UPnP is not enabled or improperly configured. It’s a plug-and-play solution if you only have one router.
Please first try the following steps:
Try to enable UPnP/NATPMP in the web administration interface for the router directly upstream from your Core
If this fails, use the YouTube instructinos above to try to manually open the port in your router’s port forwarding configuration
Make sure the IP/Port matches the Port listed in Roon → Settings → ARC
Check for any VPNs or Firewalls that might be interfering
If you continue to experience difficulties, please tag the support team and include the following information:
What is the make and model of your modem and router?
Do you have any additional network hardware, like additional routers or managed switches?
Who is your internet service provider and what is your geographic region?
Is your Modem configured in Bridge Mode so that it operates only as a modem or do you have the ports forwarded on both?
