Hey everyone. Can someone please help me setting up my home lab network?

Here is the current setup.

I have a proxmox running in my network.

vmbr0:
IPV4: 192.168.0.10/24
IPV6: 2a02:xxxx:xxxx:5400:xxxx:xxxx:xxxx:2161/64
GWV4: 192.168.0.10
GWV6: 2a02:xxxx:xxxx:5400::
VLAN aware: yes

Also my ISP delegates /62 bits of IPV6 prefixes, so 2a02:xxxx:xxxx:5400::/62.

I have installed pfSense inside Proxmox to use VLANs.

pfSense WAN:

IPV4: static 192.168.0.200
IPv6: DHCP6 2a02:xxxx:xxxx:5400::26a

VLAN100:
IPv4: static 10.100.0.1
IPv6: Track Interface WAN, with prefix ID 0

I also have enabled DHCP6 and Router Advertisment on VLAN100. (as well as DHCP on IPv4)

Firewall Rules: allow everything on ipv4 and ipv6 on WAN and VLAN100.

However, VLAN100 does not get a IPv6 address. Also all the machines on VLAN100 have ipv4 address (with internet access) but not ipv6.

For example, I have an Ubuntu, connected to vmbr0, with tag id (100). It has IPv4 but not IPv6.
Network config on both IPv4 and IPv6 are set to automatic (DHCP) on the ubuntu machine.

Also, in DHCP leases in pfSense diagnostics, I can see a row for each machine connected to the VLAN, but I don't see anything for DHCPv6 leases.

Can someone help me figure why IPv6 is not working?
