HBO Streaming: Hurricane Electric 6to4 /48 or /64 Geolocation Wrong

[bill.gertz]

To anyone having the same problem I had with geolocation services using the wrong location for /48 and /64 blocks.

We had a problem where whichever HBO geolocation service decided to use, our /48 assigned by HE is located in Ukraine. IPv4 would work fine, but the Samsung 7 Series television had no option to turn IPv6 on or off - it always set up a random non-EUI-64 global prefix address and would use that. I can't set a rule by assigned DHCPv6 or autogenerated EUI-64 address. The IPv6 address it uses changes with every reboot of the TV.  I am forced to use the MAC address.

I can picture this software demon engineer in its den: "Never mind the standards, to hell with the DHCPv6 address, never mind the well-accepted EUI-64 address, we'll just go and use an IPv6 address that'll be assigned randomly at boot time. That will make life easier for no one." As it smiles evilly to itself.

The solution was to force a fallback to IPv4 by blocking IPv6 for just the television. We created a MAC address Alias and added a rule to the LAN interface for inbound packets blocking only IPv6.

Be gone, foul demon.

Magic - HBO streaming was forced back to IPv4, and streaming is now working again.
