I now need to decide whether to sign up to an 18 month contract with Trooli who are taking orders to go live in December, or wait for Swish..

Trooli/Callflow do not seem to be that well regarded and don't have great T&Cs. The idea of switching straight after the contract term does not appeal either, with the potential for the clutter of multiple fibre cables and boxes.

We've also got Gigaclear starting to (slowly) build cabinets! Quite a lot for our village (Bagshot).

Does Swish Fibre issue a 'real' public address to the router on their connections?
I have another connection at a different location on which the router has a public address, but this is additionally natted within the providers network and hence you cannot have inbound connections.
Anyone using Swish know?

Are you *sure* it's a public address? If it's in the block 100.(64-127).x.x then it's actually a special sort of private address - a block reserved for exactly the purpose you describe, where the provider performs NAT in their own network. However, it's also not unknown for clueless providers to use random blocks of addresses that they don't own, behind NAT.

Try entering your WAN address into a "whois" server to find out who owns it.

Thanks, I didn't know that.
I'm not sure what the address used is, I'll check when I'm physically back there as I can't check remotely.
Any idea if Swish use this intermediate 100.(64-127).x.x addressing?

I learnt something today
++ Edit : Looking at this the 'intermediate nat' is called CGN : Carrier Grade NAT using 100.64.0.0/10 - RFC 6598 ++

Yes if you pay them £3/month for a static IP (See their assigned ranges at https://ipinfo.io/AS208189). Otherwise it's CGNAT.

To confirm, as per above, we use CGNAT by default, but you can purchase a static IP for £3.00 per month inc VAT.

The following 3rd party services have a free option that could offer a work around to CGNAT (depending on your requirements):

Another option would be to take the AAISP L2TP service. As of today's changes you pay:

* £10 per month for 200Mbps with 2TB limit
* £2 per month for 3Mbps with 2TB limit

This gives you an IPv6 block as well.

I would like to see Ofcom mandate IPv6 where networks are defaulting to CGNAT for IPv4.

I'd be interested in knowing when Swish is going live in Chinnor. Paying far too much for a lousy 40mb/s from BT at the moment.

I’m assuming that DDNS will still work?
