<![CDATA[Force RA to send different IPv6 gateway.]]>So this is a tad different setup.

I have a public /28 and a /64 from upstream provider and this pfsense is virtualized on proxmox. (This is a test box)

I have created the following networks: WAN, LAN, INTERNALWAN

I have set the public WAN IPv4 and IPv6 as normal.
Then I had created a Bridge (Interfaces->Bridges) to bridge the WAN & INTERNALWAN.

I then want to DHCP Server -> WAN and set the Address Pool range.
Configured DNS Servers IP, and then Set the Gateway to the "master" gateway of the /28.

Then on the proxmox I set any VMs that I want to get a public IP to the "INTERNAL WAN" and it gets the IP and all is Golden.
I'm able to use the Firewall-> Rules -> WAN rules to still only allow X ports I want through.

The issue comes with the DHCPv6 / RA. I do the same thing and all works except there aint a spot for me to set the Gateway as the proper "master" gateway. So the Server does get a IP and DNS but no Gateway IPs.

Is there a way to force the RA to send a different IPv6 rather than the pfsense's routers IP?

If I set the IPv6 manually on the "client" device all works as intended as far as the connection. The OS just isn't getting the proper gateway IP from the pfsense box... instead its getting (fe80......)

It's supposed to use it's own address. I'm not quite sure what you're trying to do, but you can have multiple gateways on a LAN and give them a priority, up to 3 of them. You can set priority on the Router Advertisement page.

Gateways on IPv6 are usually fe80 unless configured by hand.

I am using pfsense DHCP Server to assign "downstream" clients.

.. on a LAN interface.
For me, ™®, downstream are LAN interfaces.
Upstream is WAN.

I am using pfsense DHCP Server to assign "downstream" clients.
The DHCP Server's are working. Its just that the IPv6 isn't sending a gateway to downstream clients.

How does the WAN gets the correct IPv6 info (GUA, prefix(s), etc) from the upstream DHCP IPv6 server ?

The issue is the DHCPv6 / RA isn't giving me the option to set a gateway

A DHCP server uses a LAN type interface.

The WAN interface is used by a DHCP client, to obtain a IP lease (IPv4 or IPv6) from an upstream DHCP server.
