Re: Possible to handle fiber WAN connection with OpenBSD using PCIe card?

No it is not, there is a reason why tech saavy ISPs exist, and it is
because most ISPs are hesitant or outright against the idea of custom
routers.

When the ISP provides you a router they lock the credentials into the
router. I might have been wrong about openreach based ISPs because by
the look of it, although not supported by the ISP, in most cases you can
get a third party router working.

But I am not wrong about virgin media, there is no way to get rid of
their router, I have tried numerous times.

Seems like a classic case of Polarian exaggeration when it comes to
Openreach.

If the isp does not hand over your credentials you can not use a third
party router, end of story. I am not wrong here.

There is tons of smaller ISPs but they tend to be the nicer ones when it
comes to custom hardware, they do not have the money to design their own
custom routers, thus will let you source the right one for the job.

The ONLY reason why for some openreach isps you will be able to use a
third party router is due to openreach being the last mile and decides
the authentication mechanism.

> BT allow you to use your own router.

Yes I searched it, they are against it because "it is insecure", but
they do provide the credentials if you want them.

As far as I am aware, you have to get on your hands and knees and beg
them for the credentials.

VDSL (FTTC) uses a 1gbps fibre bearer, but in this case, your line cant
use it all, it can only do max 80mbps down and 20mbps up, you would
struggle to overwhelm the cabinet, compared to FTTP installations.

I am aware of this, they are working on it afaik.

You really hate them as an ISP, when did you last use them?
