In setting up a VLAN on my switch in quickly became apparent that I would also have to set up a VLAN in my USG50. I setup vlan30 in the USGl with a tag of 30 using 10.10.30.1/24 for the VLAN IPv4 address and previously unused /64 from my Hurricane Electric /48. The VLAN is configured as both a DHVP(v4) and DHCPv6 server. I run two local caching name servers with Interfaces on LAN1 (and LAN2). IPv4 is working two and from LAN1 but it appears the USG50 isnt passing IPv6 traffic between the interfaces. I believe the switch is configured correctly because my test PC gets and IPv6 address and IPv6 DNS servers from the USG50 via DHCPv6. The VLAN interface type is set to Internal and IPv6 is enabled. I noticed that there was no policy route for the VLAN to tunnel one so I add one with the same parameters as LAN1 and LAN2. IPv6 internet access is via IPV6inIpv4 tunnel. I cant reach my DNS servers on LAN1 via IPV6 from the VLAN. A ping to Google.com using its IPv6 address also fails from the VLAN.
This is the first time I have needed to send IPv6 traffic between interfaces and the first time I have setup a VLAN in the USG50. My educated guess is that I need addition IPv6 policy route(s).
