The CRS112 have the task to provide DHCP Servers to the VLANS there are two untaged ports for one VLAN with the ID666.
Everything worked fine but as I deleted a second unused bridge my VLAN-bridge stopped working. I wasn’t able to trouble shoot that so I made a reset but I'm still not able to bring it back to work. Maybe some on is able to help me.
Thank you in advance.
