[pfSense] DHCPv6 working but no gateway

[Steve Yates]

I set up a couple of 3100s at a client and their branch office, with OpenVPN connecting them together. With the LAN set to "track interface" IPv6 addresses are acquired and DHCPv6 is working. RA doesn't seem to be working since Windows PCs don't get a gateway. I know I picked modes Managed or Assisted. If I set a static IP in that range with a gateway I can get out, so IPv6 is routing. If I configure the VPN for IPv6 I can even ping across the VPN to the other router.

My understanding was if RA was enabled and everything at defaults/blank it should "just work"...am I missing something that needs configuring? I did try putting in a subnet, even though the RA page says that's not necessary.

Thanks,

Apparently pfSense 2.4.2 fixed a bug with RA not working on the SG-3100 router model:
