1x DHCP Server 2019 - multiple VLANs - what am I doing wrong?

1x DHCP Server 2019 - multiple VLANs - what am I doing wrong?

I’m having an Extreme Networks x460 Switch and 2 VLANs. On VLAN 11 there’s a Windows Server 2019 located which has 2 scopes (for the different vlans)

VLAN 11 IP Switch: 192.168.11.253/24
IP
 DHCP Server: 192.168.11.1

VLAN 193 IP Switch: 192.168.193.253/24

I’m able to ping the DCHP Server from the Switch


I did a config bootprelay add 192.168.11.1 vr VR-Default
Also enable bootprelay VLAN VLAN11
and enable bootprelay VLAN VLAN193

and last but not least: enable ipforwarding vlan11
and enable ipforwarding vlan193

When I connect a client to VLAN 193 I’m not getting an IP Adress.

The DHCP Server has a Scope for: 192.168.11.100-110 and a Scope for: 192.168.193.100-110

I found the error and it’s working now - thank you!! 
The problem was the getting back to the VLAN . The Problem was more firewall related then switch related. Best Regards, Frank PS: Wireshark did the trick

Silly question, but you have built the VLANS in your router right?
