pfSense WAN_DHCP6 gateway question
-
Strange one this (to me at least)...
My ISP is Virgin Media and they don't offer IPv6, and yet my pfSense dashboard shows both IPv4 and IPv6 gateways as being online and both with IP addresses.
The IPv4 gateway is of course pingable. The non-existent IPV6 gateway address is (again, of course) not.
So what gives? Is this a bug? Why does pfSense think there is an IPv6 gateway there when there is not? BTW, restarting the Gateway Monitoring Daemon does not fix this.
I have (probably wrongly) IPv6 Configuration Type set to DHCP6 in the WAN interface config - since this was the default set up. I guess disabling this may fix it, but I am puzzled as to why pfSense is picking up an IPv6 address and where from???
Any ideas?

By the way, changing IPv6 Configuration Type to "None" does indeed make the IPv6 gateway disappear, as expected. But still begs the question where pfSense gets the imaginary gateway address from if IPv6 is enabled, and why it reports the IPv6 gateway as being online with no packet loss, when it is not even pingable.

Is it a link-local address? fe80
x:x?Those are generated locally and are non-routable. So you would not be able to ping it from a client behind pfSense but pfSense itself may be able to ping it. The ISP can use that to route a prefix delegation across in a setup where they provide only that.
