Title: No IPv6 on WAN
Post by: jarif on July 15, 2017, 01:39:12 pm

I'm a consumer client for Telia in Finland. I have a VDSL2 modem/router from them, and it is in routing mode, and has both IPv4 and IPv6 addresses. One of the LAN ports of it is in DMZ mode, and my OPNsense firewall is connected to that.

And OPNsense does not get IPv6 no matter how I configure the DHCP6 setting. It is currently in DHCPv6 and no IPv6 address, If I set it to 6to4-tunnel it gets IPv6 address but still http://test-ipv6.com claims I do not have IPv6.

Any ideas?

What is the size of the delegation from your ISP? I would pick a /64 and assign static IP's for the WAN and LAN interfaces of OPNsense.

Ok, no other process is listening on that port ... then I have no idea ... maybe a network trace helps  to see if the provider really offers you a prefix ...

How can I do such a network trace?

Interfaces -> Diagnostics -> Packet Capture --> Select WAN Interface, Protocol should be ICMPv6 (I think) ... then press start and wait for a couple of minutes. Then download the trace and check it with Wireshark.
