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

Hello,

If I had known this, the email I just sent in response would have been
more direct :/ whoops...

Openreach has nothing to do with this thankfully, apart from being
arseholes when it comes to limiting upload speeds.

I will quote the other comment here now because I will discuss it too.

So, lets talk about UK's bad infrastructure.

The MAJORITY of ISPs WILL NOT permit using of custom routers, this
includes all the big corpas you know of. I believe you must pay for
business lines, and pay extra for the ability to use your own router for
some, and some outright refuse.

Some ISPs, such as virgin media, do support custom routers... sort of.

They force you to pass all packets through their router, but you can put
the router in modem mode and then push packets through it with a second
router, but the router is still mandatory to use.

As for the ONT's I am not sure, but the openreach modem I am using is
cracked, people spend a lot of time cracking open the software locks on
the openreach gear, this allows us to get cheap ONTs and modems without
having to pay the earth for a managed one.

As a rule of thumb, do not use a ISP which forces you to use their
router, so BT, Sky, Virgin Media etc etc etc all are a no go, you need
to find an ISP which gives you a list of routers to buy with your
installation, or which outright make it optional, these ISPs will allow
you to use your own router.

I use andrews and arnolds as an ISP, most people will be deterred, but
the reasons for picking them in my opinion:

- GPG encrypted email to support and sales team.

- IRC support during normal working hours, no need for proprietary web
chats, you can use your favourite IRC client.

- Supports custom routers, they do not ship a router or modem with your
broadband, they leave it up to you.

- Line metrics, testing tools etc, their client panel has everything you
will ever need.

Now the downsides:

- Metered, all ISPs have a "fair use policy", but A&A use a quota
system, instead of being throttled during peak hours, you will have full
access to the network until your quota runs out (If you are running
10tb/month home plan, and you manage to exceed it, you need a dedicated
line!!!), they will throttle you to ADSL speeds, which is just enough to
browse the internet.

- pricey, I pay £55/month for Business DSL, bare in mind this includes
no router renting etc, I get /32 and /29 IPv4 (I can ask for more if
needed) and a /48 IPv6 block (but this is often split into multiple /64,
and you got to make the blocks manually).

Another alternative is idnet, they support static IPv4, IPv6 support,
custom router support, and they are cheaper, provided you dont want /29
blocks as they are £24/month per block.

You might need to move ISP if you want a WAN facing router using
OpenBSD, sorry.

(as a sidenote I would like to highlight I am using Stuarts comments,
but I am replying to keya)

Good luck,
