DHCPv6 not working on RV345P - no address range available for DHCPv6

[betabites]

Hello Forum!

I'm trying to upgrade my Cisco RV345P router to allow for IPv6 traffic. On my network, I have 3 VLANs. Each vlan is assigned an IPv4 range, as well as an IPv6 range. From what I can understand - when supported - devices should be getting assigned IPv6 addresses.

Instead, all devices on all vlans are being assigned IPv4 addresses only and I'm getting the following error in my router's logs:
- dnsmasq-dhcp: no address range available for DHCPv6 request via eth3.1

Please note that on this router, I'm only able to access the web GUI. I don't believe that ssh connections are supported?

              - Use the latest firmware available for the RV345P
              - Check the DHCPv6 configuration and or if it is allowed to distribute addresses through  eth3.1
              - Check if the corresponding vlan has full ipv6 support (configured)
