Matrix: EHX PC and Matrix on a different VLAN

EHX PC and Matrix is on a different VLAN on the same switch and it is:

  1. Not being discovered on Layout Page

  2. Added manually but greyed out on the Layout Page

  3. Possible to retrieve map and see event log status

  4. Possible to apply map to matrix

  5. Possible to ping the matrix frame IP address

  6. Checked that all Windows Defender firewall settings are in place and current EHX software has been allowed


If your network setup requires the EHX PC and Matrix to sit in a different VLAN, you will need to set:

  1. IPv4 routing > Enabled

  2. UDP Relay/ IP Helper Configuration

  3. Ensure that each VLAN has its own interface IP set up and the required ports assigned to the VLAN.

For e.g. on a Cisco SG350X:

SG350X IPv4 Routing Enabled.png
Set IPv4 Routing > Enabled
Configuring UDP Relay Table

Please consider carefully when setting up networks with routing required across VLANs.
