Hallo! 

 

Ich habe meine Surround Anlage (HEOS) in ein VLAN (VLAN90) verschoben. Im VLAN20 ist mein Mobile device und steuere mit der HEOS App die Anlage. 

 

mDNS ist eingerichtet

IGMP Proxy aktiv

Multi- Unicast conversion ist off.

 

Mit ACL's trenne ich VLAN90 vom Rest.

Davor erlaube ich den Zugriff der Sorround Komponenten (IP Port Gruppe) mittels ACL auf VLAN20.

Solange ich alle Ports freischalte haut alles wunderbar hin. Wie stelle ich fest welche Ports und welches Protokoll veerwednet werden,

damit nicht alle Ports offen sind.

 

Omada V5.15.8.2

ER605 V2 V2.2.6

EAP653 (EU) V1.0 V1.1.0

Good Morning.

 

It is not mDNS it is working. It is the question which ports will be used by the sourround system in VLAN90 to communicate with the control app in VLAN20.

currently all ports are open. My intention is close all ports except those ones that are necessary. Therefore I need some network trace possibilities to see which ports are used. Description of the Surround system regarding network reauirements are very poor.
