Hi Forumites,

I'm looking into getting FTTP at home, however there is only one single provider at this location (v. rural postcode in North West England, the FTTP provider is an altnet that deployed with public money because we aren't 'commercially viable' for Openreach or anybody else). Unfortunately this provider uses the abomination known as CGNAT, which can be avoided on their business packages by taking the static IP option, but they do not (yet, they said it's planned but they can't give a timeframe) offer IPV6, which I need because the house phone system doesn't work over IPv4 NAT.

I have in the past used HE.net tunnelbroker for IPv6, however it caused quite a few different sites to have tantrums because the IPv6 address geolocated to America and not the UK.

There is a small 'specialist/enthusiast' ISP in the UK that offers an L2TP tunneling service for the express purpose of allowing customers of other ISPs to bypass CGNAT and also gain IPv6 connectivity when they can't otherwise.

My query is, therefore, given that the FTTP provider almost certainly uses PPPoE authentication (UK ISPs seem to love it rather than use the superior more modern alternatives), is it possible to set up an L2TP tunnel such that it runs over the top of the PPPoE WAN link, and if so do I need to do anything special to make it happen?

Alternatively, if anyone knows of a tunnelbroker that can provide UK geolocated IPv6 addresses, then that would certainly be an option.

Thanks all.

Would it possible to add the Intel i915 GPU drivers/firmware(DRM-KMOD) to Opnsense, either as a plugin or as part of the base install? I completely understand how ridiculous it sounds wanting GPU drivers on a headless FW appliance, but please bear with me.

I have been trying to get my firewall power usage as low as possible, and trawling the net, it would appear that the GPU driver and firmware are required in order to put the GPU into a low power state, otherwise it just burns power (anecdotal evidence on the net suggests up to 3W, which on my N-series appliances could be as much as a third of the total power draw) for no reason.

This matters to me because, as a Brit, I am lucky (HA) enough to live in the country with the most expensive electricity in the world (apparently), and it's only going to get worse. 3W 24x7 over a month is just over 2kW, which is an additional £0.50p+ a month on an electric bill for absolutely no benefit. Multiply by 12 months and it starts to get a bit ridiculous considering that 3W is doing absolutely nothing useful.

Secondly, my firewall appliances are passively cooled. The GPU is putting extra load onto the heatsink for no good reason. Being able to tell it to go away or at least sleep could well bring the system temperature down by a few degrees, which is good for the longevity of the hardware, and would also be beneficial for people living in places with relatively higher ambient temperatures where passive cooling isn't as effective.

I've tried to add drm-61-kmod using ports but the build failed part way through with a nonspecific error.
