BUG: IPv6 Prefix Delegation over PPPoE broken

Ben over 8 years ago

reported this in 9.3 aswell,

when setting up WAN Connection over PPPoE the sophos is unable to get a prefix delegated to use for IPv6.

other routers i tested are able to get a /48 IPv6 Prefix with the same connection.

Yeah, doing something like that :)
Using my old OpenWRT router. Router gets the /48 prefix perfectly. Assigned my Sophos a static IPv6 address on the WAN interface.
My internal network gets a /64. OpenWRT has a static route to this subnet. The clients are getting their address via the Prefix Advertisement.
Downside of this solution, except extra hardware and NAT, all the outgoing traffic is using my Sophos WAN IPv6 address :(

Sophos, fix it please! I'd except a bug like this to be in cheap consumer hardware, not in professional/enterprise level hard/software.

yes, but with the mikrotik you can perfectly set it up and assign a 56 prefix for example to the sophos fully working. But this can't be a permanent solution because of other problems of course. That beeing said, Mikrotik are real nice Endpoint Devices for Networking in front of a sophos for the price they cost if you want to avoid PPPoE Issues.

Sophos, I'm disappointed. Again.

I'm so glad that Sophos is a professional security/networking company, and that they finally fixed this. Because in the opensource world or consumer grade products they couldn't get this to work for years.. Oh wait.........

i could live with this bug if sophos would comment on this and says its currently not possible or too time consuming to fix. But we are just getting ignored on this one.

So.. No news is good news?

Or is ignoring and hoping the users will go away the way to go?

i bet my 2 cents on that we will get ignored because it has no business case. I really wonder why even bother with a "community" like this if it ends beeing a user to user Forum without better Sophos Feedback. I will ask at the sophos booth at the cebit fair but i do not expect a real answer.

How is it that I'm not surprised?

Glad that you confirmed, I wasn't much like removing my good 'ol OpenWRT router, reconfiguring my WAN interface, patching cables...

Hi guys,

have you tried compring the logs from the devices you are getting an assigned /56 to that of the UTM to see if that shows any point of reference that you can identify as failing?
